structure that protects the internal power, control and automation
components in the most severe applications

• The Square D Model 6 MCC reflects our commitment to manufacture

the highest quality motor control center with the structural
dependability to meet years of demanding service requirements

Innovative.
• Customer-driven features for improved usability

• Compatible with a wide range of Schneider Electric components

including Powerpact® Motor Circuit Protectors, TeSys® T Motor
Management Controllers and Altivar® AC Drives

• Available as an “intelligent” solution: pre-wired distributed I/O or with

network protocol per the customer’s specification

• “Controller Inside” programmable card on Altivar AC Drive allows PLC

“on board” the drive

Straightforward.
• Power of information is secure and simple to integrate

•  Industry-exclusive, full-depth vertical wireway

• Horizontal bus located at the top of the structure for easy installation,
inspection and maintenance without the need to remove units

• Captive horizontal splice bars to prevent bar loss and make

connecting sections quick and simple

• AC drive programming includes a “Simply Start” menu with macro

configurations for simple and fast commissioning

• Twin-handle cam mechanism works with the unit’s “hook and

hang” feature to provide proper stab alignment and allow for easy
installation and removal of units
A solid foundation.
The Square D Model 6 MCC enclosure
is specially engineered to deliver years of
rugged, dependable service. Designed and
manufactured to tackle the toughest power
and process control challenges, the Model 6
Motor Control Center features the innovations
to provide unmatched performance.

Frame
The vertical section is
made from a welded
side-frame assembly
formed from 12-
gauge steel. Internally
reinforcing structural
parts enables the
enclosure to meet or
exceed all applicable
codes and standards

Corner Channels
This exclusive profile
provides greater
cross-sectional area
and eliminates
alignment issues
during installation.
Corner channels
increase front-to-back
stability and rigidity
ensuring that plug-in
units can be removed
and installed after
years of service. Tie Channels
Increased joining surface area maintains
critical alignment and lateral rigidity to
ensure secure door closure and reduced
installation time.

Midshelf Supports
Robust midshelf supports more effectively
transfer the weight of the plug-in unit to the
Square D Model 6 MCC structure. An increased
rear-support angle transfers the stress
associated with unit removal and installation,
enhancing the structural integrity of the section.
 Sliding Horizontal
Bus Barriers
The sliding panel design provides easy
access to the horizontal bus so preventative
maintenance is quicker and easier. Using
a non-conductive material enhances
operator safety when performing predictive
maintenance. An integrated track system
means you do not need to remove the panels
to splice or inspect the horizontal
bus connections.

Automatic Bus Shutter

Ideal for vertical bus and unit stab connection
applications, its simple, logical design
automatically opens and closes for convenient
insertion or removal of motor control center
units. Placing the actuating parts outside of
the bus area reduces wear and shutter jamming
– a common problem with “sliding” designs.

Shrouded Power Stabs

Protects the power stabs against damage
during unit maintenance and provides a
self-aligning system for installation of units
and connection to the vertical bus.

seismically certified have been qualified

The power and control you need.
Where and how you need it.
Whether your installation features small motors and tight spaces or large motors and rows of machinery, the Square D
Model 6 MCC can accommodate the starters and electrical distribution devices you need – as well as the automation
and monitoring your application demands.
