PowerPact® R-frame Main Circuit Breaker on Left Power-Style® QED-2 switchboards provide a convenient and economical
with I-Line® Distribution Section on Right
means of distributing electric power. These enclosed, free-standing
structures contain circuit breaker or fusible overcurrent protection for
services rated up to 5,000 A with a maximum voltage of 600 Vac.
Power-Style QED-2 switchboards are custom-made for use as service
entrance equipment or as distribution centers in commercial, institutional,
and industrial applications.
An auxiliary section is also available for cable or bus transition or to provide
additional space for connecting the service conductors to the line side of the
main. The auxiliary section is a full-height section with a depth to match that
of the adjacent section. It can contain customer metering or through bus and
incoming lug pads.
The QED-2 frame allows various special components to be mounted in the
switchboard. These components include automatic throwover systems,
transfer switches, and special metering systems. This flexibility means the
QED-2 switchboard can meet customer requirements on the most
complicated applications.

Structures
The QED-2 switchboard frame has been designed to provide a sturdy
platform on which to build Schneider Electric switchboard products.
Individual switchboard sections are built from formed steel channels and
angles, then secured together with thread-rolling screws. These
thread-rolling screws, when compared with regular self-tapping screws,
provide superior torque and strip-out resistant qualities.
Section dimensions are determined by the type, size, quantity, and
arrangement of the components and devices being installed.
Each section features a removable one-piece top plate, which makes
locating the top conduit entry simple. When extra height is required,
Schneider Electric can supply a 12 in. (305 mm) or 24 in. (610 mm) high
pullbox. (The pullbox is not available with NEMA Type 3R enclosures.)
All covers, doors, and frames are made of formed steel for extra rigidity. A
deep front corner channel and side plate covers the sides. The back is
covered with removable plates that have formed edges. All covers are
secured with slot/hex head thread rolling screws which greatly minimize the
NEMA Type 3R Enclosure Over Three Sections chances of thread strip-out.
The standard paint finish on all Power-Style QED-2 switchboards is an
ANSI #49 medium light gray baked enamel over an iron phosphate
pretreatment. Non-standard finishes are an available option when specified.
QED-2 switchboards are available in either NEMA Type 1 indoor or Type 3R
outdoor enclosures.

Each QED-2 section 3,000 A or less has removable lifting bars and is clearly
labeled with handling procedures. The sections are shipped separately to
allow the installer extra flexibility when moving the sections to the desired
location. Once in place, the sections are secured together, linking the
strength of each frame. Optional multiple-section shipments do not have
lifting bars.

Bussing

Through Bus
The heart of a switchboard is the horizontal through bus which connects
the individual section bussing. The through bus is available in ratings from
1,200–5,000 A. Power-Style QED-2 through bus uses aluminum or copper
rectangular 0.25 in. x 1.5 in. (6 mm x 38mm) or 0.25 in. x 2 in. (6 mm x 51 mm)
bus bars. Through bus rated 4,000 A has eight bus bars per phase.
Connections are made by using an “E” connector assembly.
Bus ampacity ratings have been determined from UL 891 heat rise testing.
This method is the most accurate, since actual tests are used for
determining optimal bus sizes.
A 100% neutral bus is provided on 3-phase, 4-wire (3PH4W) and
1-phase, 3-wire (1PH3W) systems. Ground bus is standard and matches
the type of through bus. Optional, increased-size ground bus is available.

“E” Connector Assembly

The “E” connector assembly eliminates the alignment problems associated

4,000 A Through Bus Assembly with conventional bus bar connections. The “E” connector assembly,
consisting of an “E” connector, carriage bolt, conical washer, and hex nut,
requires only one wrench to tighten. This assembly is used on splice
connections and connections to through bus from the panel bus. By
providing more uniform pressure over the contact surface, a highly efficient
and cooler connection is obtained.

“E” Connector on 2,500 A Through Bus

Captive Splice Bars

Captive splice bars are provided on through bus connections through
2,500 A. They provide easy installation and reduce the chances of losing
parts during installation. Splice connections are made up of splice bars and
the “E” connector assembly. For splicing convenience, customers can
access the through bus bars in QED-2 main and distribution sections from
the front of the switchboard. Slots are provided in the splice bus for ease of
assembly. For addition of future sections, through bus is extended to the
sides as standard in all sections.

Group-Mounted Distribution Sections

Power-Style QED-2 switchboard distribution sections are available with
either an I-Line or QMB group-mounted distribution panel. Each of these
interiors mounts to the frame front corner channels with horizontal mounting
rails. Connectors secured to the through bus with the “E” connector
assembly bring power into the center of each interior bus. The vertical bus
feeds power to each branch disconnect. When a neutral is required, it is
located at the side of the QMB vertical bus assembly or at the side of the I-
Line circuit breaker mounting pan. This convenient neutral location provides
for front accessible neutral connections. Ample wireway space is provided
for the load side cabling of branch disconnects.
Schneider Electric molded case circuit breakers are available in I-Line
plug-on group construction. In this construction, the line end of the circuit
breaker plugs directly onto the I-Line panel bus assembly. Branch circuit
breakers can be quickly and efficiently installed and wired from the front of
the switchboard. I-Line circuit breakers are keyed to mounting slots in the
support pan to provide automatic alignment and reduced installation time.
The circuit breakers are then secured to the pan with screws. I-Line
switchboard sections are available in single row or double row construction.

Layout Instructions

All dimensions and arrangements shown in this manual are for estimating purposes only and may
change without notice due to changes in equipment design. Certified drawings showing the
arrangement and dimensions of any switchboard can be supplied by Schneider Electric upon request.
All section depths shown are considered minimum for most switchboard arrangements. However, due
to complicated equipment or bussing arrangements, it is sometimes necessary to increase the
switchboard depth beyond that indicated in this manual.
Schneider Electric cannot supply switchboards with smaller dimensions than those considered by the
company to be the minimum necessary to (1) obtain satisfactory operation or (2) permit ease of
installation of the switchboard with reasonable effort by the customer.
For quick layout drawings, see pages 23–26.

Layout Selection Procedure

When determining a layout for Power-Style switchboards, use the following procedure:
1. Determine the physical location of the switchboard and the connected loads it is to supply.
2. Make a single-line diagram of the components.
3. Determine the bus rating required and the minimum ratings for the switchboard (based on voltage,
available short circuit current, and load).
4. If equipment is a service entrance switchboard, coordinate with the power company regarding
feeder equipment and metering provisions.
5. Determine method of incoming power (I-Line busway, cable, etc.), and select the main device.
6. Determine utility and/or customer metering, if necessary.
7. Decide on branch devices to use; select from branch device section.
8. Determine any special cubicle or bussing features.
9. Sketch a front elevation, including single-line locations.
10. Write specifications or ordering information.
11. Provide cable lug details and conduit entry/exit location for mains and feeders.

Terminal block
(Network communications)

“Intelligent devices“

Network Communications

One or more “intelligent devices” such as circuit monitors, circuit breakers, or relays are wired in an
RS-485 daisy-chain network as a basis for all Transparent Ready Equipment (TRe). In some cases,
the web server is external or reserved for the future. In this case, the RS-485 communications are
wired to a terminal block for the end user.
In TRe-1 and TRe-2, HTML web pages designed specifically for the power equipment lineup are
loaded into the equipment at the factory. In the past, this type of functionality required the development
of “custom” HTML pages by an integrator or an HTML-savvy end user. Today, Schneider Electric
pre-defines the most popular web pages and provides these “custom” HTML web pages as part of our
standard offer.

TRe-1 (with ECC)

Some TRe-1 applications require the use of a PowerLogic® circuit monitor, Series 3000 or 4000, and
an Ethernet communications card (ECC) that slides into an option slot of the circuit monitor. CM3000
and CM4000 circuit monitors with ECC have been available in most Square D® brand power
equipment since July 2002.
Other TRe-1 applications require the use of a Series 800 PowerLogic power meter and an ECC
(PM8ECC). PM800 power meters with PM8ECC have been available in most Square D brand power
equipment since January 2008.

TRe-1 and TRe-2 (with EGX)

Some TRe-1 and all TRe-2 use a PowerLogic EGX (Ethernet communications gateway) to provide
real-time power equipment lineup data. Ethernet gateways have been available in Square D brand
power equipment since 1995.

Electronic Trip Systems

M-frame circuit breakers are available with the ET 1.0 electronic trip system. P-frame and R-frame
circuit breakers are available with either the ET1.0I basic electronic trip system or the Micrologic
electronic trip system. The Masterpact NW (stored energy) circuit breakers are available with the
Micrologic electronic trip system. The sensing system responds to the flow of current through the
circuit breaker.

Thermal Imaging

The thermal imaging function protects the cables or bus bars from overheating in case of low
amplitude repetitive faults. Such overheating can be due to repetitive motor starting, fluctuating load,
intermittent ground faults, or subsequent closing after a fault. Traditional electronic protection does not
protect against repetitive faults because the duration of each overload above the pickup setting is too
short to achieve effective tripping. Nevertheless, each overload involves a temperature rise in the
installation, the cumulative effect of which could lead to overheating of the system.
The thermal imaging function remembers and integrates the thermal heating caused by each pickup
setting overrun. Before tripping, the integrated heating value reduces the associated time delay and,
therefore, the reaction of the trip unit is closer to the real heating of the power network system. After
tripping, the function will also reduce the time delay when closing the circuit breaker on an overload.

True RMS Current Sensing

The sensing system responds to the flow of current through the circuit breaker. The trip unit samples
the current waveform to provide true RMS protection through the 15th harmonic. This true RMS
sensing gives accurate values for the magnitude of a non-sinusoidal waveform. Therefore, the heating
effects of harmonically distorted waveforms are accurately evaluated.
The Micrologic H trip unit provides additional sampling of the waveforms to measure and provide
waveform capture of harmonic distortion to the 31st harmonic.

ET Trip System

ET trip units are available with M-, P-, and R-frame UL/IEC circuit breakers. The trip units are not
field-interchangeable and do not accept any communications or other trip unit accessories. The trip
system uses a set of current transformers (called CTs or sensors) to sense current, a trip unit to
evaluate the current, and a tripping solenoid to trip the circuit breaker.

ET1.0 (M-Frame only)

The ET1.0 trip system is available on M-frame circuit breakers and is equipped with fixed long-time and
adjustable instantaneous (LI) tripping functions only. The long-time pickup is 1.0 x sensor rating (In),
while the instantaneous pickup is adjustable (dial settings from 2–10 x In) with no intentional time delay.

ET1.0I (P-Frame and R-Frame only)

The ET1.0I trip system is available on both P-frame and R-frame circuit breakers and is equipped with fixed
long-time and adjustable instantaneous (LI) tripping functions only. The long-time pickup is 1.0 x sensor
rating (In), while the instantaneous pickup is adjustable (dial settings from 1.5–12 x In) with no intentional
time delay.

ET1.0M (P-Frame only)

The ET1.0M trip system is only available on P-frame motor circuit protectors and provides protection for
short circuit conditions only. The trip unit has a single adjustment for instantaneous pickup that, if
exceeded, trips the circuit breaker with no intentional delay. Instantaneous trip dial settings are
2–16 x In for 600 A circuit breakers and 1.5–12 x In for 800–1,200 A circuit breakers.

Micrologic® Electronic Trip Systems

All Masterpact NW circuit breakers are equipped with the Micrologic trip system as standard. The
P-frame and R-frame electronic trip circuit breakers can be equipped with the optional Micrologic trip
systems listed in the following table.

Micrologic P Trip Unit — 5.0P 6.0P
Micrologic H Trip Unit — 5.0H 6.0H

Trip units are designed to protect power circuits and loads. Micrologic trip systems use a set of current
transformers (called CTs or sensors) to sense current, a trip unit to evaluate the current, and a tripping
solenoid to trip the circuit breaker. Adjustable rotary switches on the trip unit allow the user to set the
proper overcurrent or equipment ground-fault current protection required in the electrical system. If
current exceeds a set value for longer than its set time delay, the trip system opens the circuit breaker.
Alarms can be programmed for remote indications. Measurements of current, voltage, frequency,
power, and power quality optimize continuity of service and energy management.
Integration of protection functions in the Application Specific Integrated Circuit (ASIC) electronic
component used in all Micrologic trip units guarantees a high degree of reliability and immunity to
conducted or radiated disturbances. On Micrologic P and H trip units, an independent microprocessor
manages the advanced functions.
Circuit breakers are shipped with the trip unit long-time pickup switch set at 1.0 and all other trip unit
adjustments set at their lowest settings. A qualified consultant or plant engineer must determine the
actual settings required for a specific application. A coordination study is recommended to provide
coordination between all circuit breakers in the distribution system.

Can only be used in combination with a PowerPact R-frame main circuit breaker.

Unlisted Utilities

There are two ways to have utility compartments built for utility companies that are not listed.
1. The unlisted utility company has no specific design, and just a bussed compartment in the service
entrance equipment is required for installing CTs.
For this application, select the listed utility company that best meets the unlisted utility requirements
and provide the name of the unlisted utility company. Schneider Electric will build the utility
compartment to the design standards of the listed utility selected. The “record” drawings will show
the name of the unlisted utility.
2. The unlisted utility has a specific design and does not allow deviation.
For this application, custom design and fabrication are required. The specific utility requirements
will have to be provided for pricing and design.

Definitions

Cold Sequence Metering—In cold sequence metering, the main disconnecting device is placed ahead
of (on the line side of) the current transformer compartment. In this arrangement, the current
transformer compartment can be de-energized by switching the main circuit breaker to the OFF
position.
Hot Sequence Metering—In hot sequence metering, the main disconnecting device is placed behind
(on the load side of) the current transformer compartment. In this arrangement, the current transformer
compartment is always energized.

QED-2 Quick Connect Generator Switchboards

The Square D® brand Power-Style® QED-2 Quick Connect Generator Switchboard from Schneider Electric
addresses the growing market need for switchboards with quick connect terminals to facilitate connecting
generators for temporary back-up power. Common applications include facilities such as nursing homes,
hospitals (supplemental equipment not fed by emergency power), and stores with perishable products, that
are sensitive to power outages, but typically do not have or require backup power sources.
Customers have become more sensitive to the need for temporary back-up power to reduce the
duration of disruptions due to hurricanes, tornadoes, snow storms, brownouts, and other
circumstances that can result in prolonged power outages. In these situations, a mobile generator can
be brought in to get a facility back on line quickly.

Surge Protective Devices (SPD)

These devices help protect AC electrical circuits from the effect of lightning-induced currents,
substation switching transients, and internally generated transients resulting from inductive or
capacitive load switching. They are available in I-Line mount, QMB mount, or individual mount in the
instrument compartment.

Common Features

• UL 1449 Recognized, 3rd edition

• Copper internal bus for the SPD
• Individually fused suppression modules
• On-Line diagnostics continuously monitor unit
• Thermal cut-out
• Solid state, bi-directional
• Front panel alarm with test/silence switch
• Front panel operational indicators (LEDs) to indicate loss of protection or circuit fully operational
including N-G
• High energy parallel design for Category A, B, and C3 applications
• AC tracking filter with EMI/RFI filtering up to -50 dB from 100 kHz to 100 MHz
• Ratings available (per phase): 100 kA, 120 kA, 160 kA, 200 kA, 240 kA, 320 kA, 480 kA
NOTE: 320 kA and 480 kA devices can only be mounted in an instrument compartment. If you
have a utility compartment, please contact your local Schneider Electric representative.

Options

• Surge Counter
• Remote Monitor

I-Line Mount SPD

• Comes with circuit breaker disconnect

• Requires 13.5 in. interior mounting space I-Line SPD

QMB Mount SPD

• Comes with QMB unit disconnect

• Requires 9 in. of interior mounting space

Instrument Compartment SPD

• Comes with circuit breaker disconnect QMB SPD

• Requires a 19.5 in. instrument compartment

Reducing Impedance with Internal and Integral SPDs

Internal SPDs do not require the extra several feet of conductor used by externally mounted devices.
This is key, because every foot of conductor can increase potentially damaging let-through voltage by
as much as 160 V.
Integral SPDs are an internal installation where the suppression modules are mounted directly to the
phase bus bars. The elimination of cables and their impedance in the SPD connection gives the lowest
possible let-through voltage.

Seismically Qualified Switchboards

Power-Style QED-2 Switchboards have been seismically qualified to meet the seismic provisions of
the International Building Code (IBC), California Building Code (CBC) and ASCE/SEI 7 based on
triaxial shake table testing following the code recognized test protocol ICC ES AC156. An independent
test facility conducted all qualification shake table testing to verify compliance to an Ip = 1.5 by
verifying post test equipment functionality as required by ASCE 7 for equipment which is part of a
seismic designated system.
The shake table earthquake simulation subjected the Power-Style QED-2 test specimens to dynamic
demands which can be more severe than the code design earthquake for most locations. A certificate of
self certification is available on request from your local Schneider Electric representative. The certificate is
based on site specific code defined seismic demand requirements for the installed location information
supplied to Schneider Electric.
The qualified QED-2 equipment must be installed, anchored, and restrained in accordance with
Schneider Electric installation guidelines (see factory supplied drawings and current instruction manual
for additional technical information) and the engineer of record. Anchorage of equipment to the primary
building structure is required to validate seismic certification of the equipment. The structural engineer
or design engineer of record is responsible for design of the code compliant seismic restraint system
for the building equipment. Schneider Electric is not responsible for the specification and performance
of seismic restraint and anchorage systems.

Manufacturer’s Certification

As long as the seismic capacity of the equipment exceeds the site-specific demand, a certificate can
be generated and issued.
Schneider Electric ensures that code compliance verification is as simple as supplying the job site
address. Our certificate clearly states the code requirement and our equipment capability.
This simplicity eliminates the need for the design professional to translate code criteria into an
equipment requirement, and then sort out less-than-clear manufacturers’ test results to verify
compliance to the site-specific code requirement of the project.
For sample certificate and compliance notes, see pages 42 and 43. Contact your local Schneider
Electric representative to obtain a seismic certificate.

by more than 125 V.

Shipping Splits

Switchboards shall be separated into shipping blocks. Each switchboard section shall be capable of
being handled individually with the use of removable lifting bars (where practical) or rollers, and shall
be clearly labeled with proper handling procedures.

Methodology and Intended Use

Short-circuit currents are calculated by dividing the secondary full load current of the transformer,
based on the self-cooled kVA rating, by the arithmetic sum of the transformer and primary system per
unit impedances (assumes transformer X/R identical to primary system X/R). Vectorial addition of per
unit impedances produces slightly higher short-circuit currents.
Motor contribution adds to the available short-circuit current. Motor contribution is based on four times the
motor full load current (assumes average motor impedance of 25%). Connected motor load is assumed
to be 50% at 208 V or 100% for 240 V and above based on the full load amperes of the transformer.
Short-circuit values are based on the percent impedance (%Z) shown. Per NEMA and ANSI standards,
actual %Z can vary +/-7.5% due to manufacturing tolerances for transformers shown with 5.75 %Z (2.0
%Z and 4.5 %Z are minimum values). If desired, account for the minimum tolerance by multiplying the
XFRMR (Transformer) Alone short-circuit values in the table by 1.081 if the %Z is 5.75%. Motor
contribution can be added using the previously mentioned methodology.
Due to transformer design differences, %Z can vary for different types of transformers of the same
kVA rating.
Short-circuit currents in the table apply when system power factor is greater than the tested value
(X/R is less than the tested value) for the type equipment involved.

Test pf and X/R Ratio

Short-circuit currents in the table are given in RMS symmetrical amperes. For a system X/R ratio
greater than the test X/R ratio of the overcurrent device in question, the available fault current
equivalent RMS symmetrical duty for comparison must be adjusted by a multiplying factor greater than
1.0. The fault current will increase.
See IEEE Std. 242-2001 (Buff Book) and IEEE Std. 1015-1997 (Blue Book) for details.
