Product Descripton
Control power transformers from Schneider Electric set the industry standard for
design innovation and performance. They are designed with low impedance windings
for voltage regulation, and can accommodate the high inrush current associated with
contactors, starters, solenoids, and relays.
A variety of designs are available to meet the diverse needs of panel builders and
machinery OEMs. The versatility of the control transformer line offers unparalleled
options for design engineers.

The Global Product Offering—Type T

Type T is the most popular and complete line of control transformers. It comes with
unmatched design innovations for top performance and is manufactured using the
most advanced insulating materials. The Type T control transformer is a solid choice if
size and cost are of concern.

Transformers with Fuse Block Protection—Type TF

Schneider Electric offers both product lines with factory installed overcurrent
protection fuse blocks. Type TF transformers consist of two primary fuse blocks and
one secondary fuse block, a configuration that meets the majority of overcurrent
needs by panel builders and machinery OEMs. Since the fuse blocks are pre-wired
and mounted on top of the transformer, the Type TF transformers have the same
footprint as the Type T unit. This design frees up space normally used for separate
fuse blocks.
We also have an extensive fuse block offering for custom applications. See the
overcurrent section of this catalog for full details.

Leaded Control Transformer Line

Schneider Electric offers transformers with internally pre-wired 24-inch primary and
secondary leads, instead of terminal boards, to make installation easier and faster for
many applications. These are only available for single voltage primary and single
voltage secondary applications.

MultiTap
Schneider Electric offers Type T transformers in the MultiTap version. The MultiTap
control transformer was designed to respond to the increased need for voltage and
stock flexibility. It combines multiple primary voltages with one or more secondary
voltages, all in a single transfomer.
The most flexible MultiTap voltage is the Universal, available on the Type T product
line only. It allows for standard primary voltages of 208–600 V and 110, 115, or 120 V
secondary voltages.

Class 9070 Type T Transformers

Type T Transformers
The Type T units are designed for the global market and are a great choice when size
and cost are of concern. This is our most popular and complete offering of industrial
control transformers. The following features are included:
• 50/60 Hz rated
• Customer installed accessories (FingerSafe™ covers, fuse blocks, fuse clips)
• Type T transformers are designed with various temperature classes:
◦ 25–150 VA with a 55°C (131°F) temperature rise, 105°C (221°F) insulation
◦ 200–350 VA with a 80°C (176°F) temperature rise, 130°C (266°F) insulation
◦ 500–5000 VA with a 115°C (239°F) temperature rise, 180°C (356°F) insulation
Schneider Electric manufactures a wide variety of voltage combinations for control
transformers. The voltage combinations are expressed as “Voltage Codes”, and are
embedded within the catalog number of the transformer. Standard codes are listed. If
the voltage combination you need is not listed, please call your Schneider Electric
distributor for assistance.

CE Marking
Industrial control transformers (ICTs) entering the European Union (EU) after January
1, 1997 are required by EU standards to have CE marking or Declaration of
Conformity to CE. EU documentation requires compliance with specification EN 61
558 of the Low Voltage Directive. Type T ICTs from Schneider Electric comply with this
specification, which adhere to, and are accepted by, EU standards. A Declaration of
Conformity for all Type T units is available upon request.
Because of different overload criteria in the CE specification, Schneider Elecric dual
rates these transformers for UL VA, cUL VA, NOM VA and CE VA ratings (see “Type T
VA Ratings” table). Because they are widely used with control circuit panels, ICTs are
also required to comply with EN 60 204 and EN 61 558 in these applications. The
Type T transformer line complies with EN 60 204 when FingerSafe™ covers are
installed.
For more information regarding CE marking, please contact your local Schneider
Electric field sales office.

Type T Transformers Selection Guide

1. Determine inrush and sealed VA of each coil in the control circuit and VA of all
other components.
2. Total all sealed VA of all operating coils and other loads VA (determines minimal
VA size required for the circuit).
3. Total the inrush VA of all coils that are starting at the same time and all loads and
coils that are running (using the regulation chart to give possible units to be
used).
4. Take VA size from step 2, go to standard VA size in chart below. Make sure inrush
VA from chart is greater than total VA from step 3. If not, go to next larger VA size
and repeat.
If supply voltage is stable and fluctuates less than 5%, we recommend use the 90%
secondary voltage column. If supply voltage is not stable and fluctuates more than
10%, we recommend use the 95% secondary voltage column. Another
recommendation is that one that never use the 85% secondary voltage column since
magnetic devices lose life expectancy if they are continuously started at 85% of rated
voltage.

Example:
This example assumes the following:
• Two NEMA size 0 contactors do not start together, but one could be ON when the
other starts.
• One NEMA size 2 contactor can start with either of the other contactors.
• One pilot light at 2 VA
1. VA and inrush are:
• NEMA 0: sealed 27 VA; inrush 245 VA
• NEMA 2: sealed 37 VA; inrush 311 VA; pilot light 2 VA
2. Total VA: 27 + 27 + 37 + 2 = 93 VA
3. Total inrush VA: 245 + 311 + 27 + 2 = 582 VA
4. From Regulation Chart for Type T at right below:
• VA minimum unit; inrush 499 VA will not work at 90%
• VA (next standard size); inrush 666 VA will work at 95%

Tapped Secondary D65: Both outputs fully rated for non-simultaneous loading, and
simultaneous rated for any combination that does not exceed the nameplate VA
rating.
Separate Windings Options: All voltage codes offer fully rated non-simultaneous
loading, and simultaneous rated for any combination that does not exceed the
nameplate VA rating.
Features of separate windings:
1. Allows two isolated control circuits, 24 V and 120 V, from the same device
2. Wire sizing for circuits for each voltage not highest current for common when
simultaneous loading. (no common)
3. If a common is required, it can be obtained with a jumper kit.

Fuse Protection Class 9070

Fuse Protection
UL Standards and the National Electrical Code® require primary protection for Control
Transformers, and many applications require secondary protection. Historically, the
fuse options supplied by transformer manufacturers were designed for Line-to-Line
primary (480 V) and Line-to-Neutral secondary (120 V).
Schneider Electric’s line of fuse options allows customers to obtain both factory- and
field-installed fuse blocks. Factory installation saves you time and labor. For both
options, the transformer footprint is identical to a Type T transformer of equivalent
voltage, because the fuse block is mounted above the transformer or on the
transformer terminal blocks. This frees up space normally used by separate fuse
blocks.
Schneider Electric offers the most complete offering of fuse options to meet all
applications for protection of the transformers and load applications. These are
broken down into Line-to-Line and Line-to-Neutral protection options for both primary
and secondary. Due to space limitations of the transformers, not all options are
available for every VA size. Also, all fuse blocks supplied by Schneider Electric are 30
A fuse blocks, which limits the VA for each voltage.
All primary fuse blocks supplied by Schneider Electric require rejection style fuses.
Rejection style fuses offer 100,000 AIC protection to comply with UL Standards. (Non-
rejection style primary fuse blocks are available by request only and can be quoted
through your Schneider Electric field sales office.)

Class 9070 Application

Application
In preparation for connecting power to the primary side of dual voltage single-phase
transformers, it's necessary to first wire the two windings in either series or parallel to
match the incoming voltage. An example of this is common transformers with a
primary voltage description of 240 x 480. The windings are rated for the lower of the
two voltages show on either side of the 'x'. Connecting the windings in series allows
for the higher of the two voltages. Connecting the windings in parallel allows for the
lower of the two voltages.

Application Class 9070

Example of a typical application

• OEM customer base source voltages in United States: 208, 240, or 480 volts
(From past shipments 480 is 65% of the business, 208 is 20%, and 240 is 10%)
• 5% of business goes into Canada and needs 600 volts; customer always knows
when equipment goes to Canada.
• Load requirement is for a 500 VA transformer, load is 120 volt control

Class 9070 Technical Data

Technical Data
50/60 Hertz
Transformers that are dual rated for 50/60 Hz are truly global units and no derating is
required for voltages or VA. Type T are 50/60 Hz.
Base Plates
The development of welded cores has allowed the incorporation of base plates on
larger VA transformers. Base plates are usually welded to the core of the transformer
for a solid connection to the transformer. They allow manufacturers to offer more
standardized mounting for specific VA sizes by allowing multiple core stacks.
Available for Type T transformers only.
Touch-Safe Terminals
Being able to offer touch-safe terminals is increasing in importance. Currently all
equipment that must comply with EN 60-204 (Machine and Low Voltage Directives)
must have some type of barrier for live parts. Besides the CE standard listed above,
domestic customers are requiring barriers on live parts with voltages above 460 V.
These customers allow Plexiglas® covers to be installed for these barriers.
Type T transformers can be made finger-safe by using snap-on covers that are
removable with a screwdriver or other flat tool. Schneider Electric offers Fingersafe™
covers, which are sold separately. See Fingersafe™ Covers (not supplied with unit) –
Compliant with IP2X per EN-60529, page 48for ordering information.
Formed Terminal Board
Formed terminal boards are used on multiple VA ranges and different voltage
combinations. This allows the manufacturer to punch jumpers for customer
interconnections and gives the customer the same basic layout for all units. The snap-
on covers for touch-safe terminations also are available on units with formed terminal
boards. Available for Type T transformers only.
Varnish Vacuum Impregnation
This is a manufacturing process for the core and coil of industrial control transformers.
The transformer is put into a tank of varnish, then the varnish is put into a vacuum,
causing the varnish to be forced throughout the coil and core. After being vacuum
impregnated, the units are cured in an oven to seal the varnish. The varnish is
absorbed by any paper insulation system and coats other insulation with another layer
of electrical strength. The process causes the coil to have a very tight connection
because it is completely bonded and mechanically very strong. The cores are also
tightly bonded with the varnish, causing the units to have better heat transfer and less
vibration noise.
Schneider Electric uses this process on all control transformers, using a clear varnish
with optimum electrical characteristics.
