General Information
General Description
Allen-Bradley CENTERLINE®Motor Control Centers (MCCs) consist of
one or more vertical sections containing electromagnetic and/or solid state
control devices that are prewired and tested within modular (plug-in) or frame
mounted (hard-wired) units.
CENTERLINE Motor Control Centers are designed in standard widths of
20” (508 mm), 25” (635 mm), 30” (762 mm), 35” (789 mm) and 40” (1016
mm). The standard front-mounted depths of an MCC are 15” (381 mm) and
20” (508 mm), in addition back-to-back mounted depths of 30” (762 mm) and
40” (1016 mm) are also offered. The standard height of an MCC is 90” (2286
mm). A 70.5” (1791 mm) high section is also available. All MCC sections are
supplied with top and bottom horizontal wireways. Most sections include
vertical wireways. Each 90” vertical section can accommodate up to 6.0 space
factors or 78” (1981 mm) for units.
Units (buckets) are designed in increments of 0.5 space factors. Each 0.5 space
factor is approximately 6.5” (165.1 mm) high. Units are designed as either
removable (plug-in) or frame-mounted (non-plug-in).
Individual units house a wide variety of power and logic devices. Plug-in units
are mounted on unit support pans within the section. Stab assemblies located
on the back of the unit plug onto the vertical bus. A mechanical interlock
prevents the unit door from being opened while the unit is energized. An
additional mechanical interlock prevents the unit from being plugged-in or
unplugged when the disconnect is closed.
Line power is distributed throughout the MCC via an isolated bus work
structure. The main horizontal bus is located in the center of each section.
Standard, center-fed, 300 ampere rated vertical bus supplies power to the
individual units above and below the horizontal bus for an effective 600
ampere capacity, allowing virtually unrestricted unit arrangement. An optional
600 ampere vertical bus provides 1200 ampere effective rating.

Nameplate Data
Each MCC section has a nameplate located on the enclosure or vertical
wireway door. See Figure 1.1., section nameplate information includes:
•Catalog Number / Serial Number
•Series Letter of Section
•Bus Bar Voltage and Current Rating
•Section Number
•UL and cUL Certification Marking
•UL Registration Number
•Enclosure Type

Each plug-in and frame mounted unit also has an identification label. The unit
label is located on the interior of the bottom plate of plug-in units or on the
interior right hand side plate of the frame mounted units, see Figure 1.2.
The unit label for each plug-in or frame mounted unit includes:
•Catalog Number / Serial Number
•Series Letter of the Unit
•Voltage Rating
•Unit Location
•UL and cUL Certification Marking

General Information 1-3
Motor Control Center
Sequence Numbering
CENTERLINE Motor Control Centers are designed so functionality is not
affected by the section installation order, i.e. vertical section numbering
sequence order.
All MCC sections carry a serial plate which identifies vertical section sequence
numbering, e.g. MCC section 1 of 1, 1 of 5, etc. See Figure 1.3.
Figure 1.3 Section Nameplate
Sections are numbered to match factory-supplied MCC elevation drawings.
Numbering each section helps installers and users easily identify motor control
centers, sections and units. If there are questions about section numbering
during field installation, inspection or operation, the following instructions can
provide guidance on equipment acceptability, listing and certification.
CENTERLINE MCC sections can be installed or added as follows:
1. In non-sequential order
2. Addition of a single section (add-on section)
3. Addition of multiple sections (add-on lineup of sections)
4. Addition of single section or multiple section between MCC sections.
If sections are added to an existing lineup and not installed in sequential order,
the installation should not be considered a misapplication or in conflict with
Underwriter Laboratories (UL) listing and Canadian Standards Association
(CSA) certification.
The paramount criteria for additions of sections to existing MCCs is matching
the horizontal bus electrical and ingress protection (enclosure type) ratings for
the total MCC line up, i.e., the voltage, current rating, short circuit withstand
and NEMA enclosure type (IP rating) for all sections must match.
Non-sequential numbering may not create a functional or listing/certification
issue. However, motor control centers should be installed in sequential order.
Installing MCCs in sequential order helps ensures proper installation and
ensures that factory-supplied documentation matches the equipment.

1-4 General Information
UL/CSA Marking
CENTERLINE Motor Control Centers (MCCs) are listed by Underwriter’s
Laboratories, Inc. (UL), Standard for Safety UL 845 and certified by the
Canadian Standards Associate (CSA), Standard C22-2, No. 14.
Due to standards harmonization, a motor control center may also carry the
cUL designation. cUL is comparable to CSA certification.
Vertical sections and units are labeled independently. It is possible to have
combinations of labeled and non-labeled sections and units in the same motor
control center.
Vertical sections and structure options that are UL listed and CSA/cUL
certified are marked accordingly. All components in a UL or CSA listed section
must be UL listed and cUL/CSA certified. The UL and/or CSA/cUL
designation is an integral part of the section nameplate. See Figure 1.1.
Units and unit options that are UL listed and CSA/cUL certified are marked
accordingly. All options and components in a UL and/or cUL/CSA listed unit
must be UL listed or recognized and/or cUL/CSA certified. The UL
designation is located on the interior of the bottom plate of plug-in units or on
the interior right-hand side plate of frame mounted units. See Figure 1.4.
Figure 1.4 UL Label Designation for Units
Short Circuit Rating Label
Motor control center vertical sections that are UL listed and/or CSA/cUL
certified will carry a short circuit rating label. The short circuit rating label for a
vertical section is located on the inside of the vertical wireway door of standard
sections or on the interior right-hand side plate of special width sections. See
Figure 1.5.

(1) When installing unit in topmost location in vertical sections, care must be taken to comply with the 2005 National Electrical Code (reference code: Article 404.8 and UL 845)
6’7” (2000 mm) unit handle-to-floor height limitation. A unit operating handle extender (2100-NE1) is available which provides 3” (76.2 mm) added height flexibility.
(2) When Bulletin 2100, 0.5 space factor units are ordered unassembled or ordered for existing sections, a centralized wiring diagram holder kit (2100H-WDH) should be
ordered.
(3) Permits installation of 0.5 space factor plug-in units in existing series E through J Bulletin 2100 vertical sections.
(4) Replacement and renewal parts are no longer supported. Consult MCC Technical Support at 1-800-646-5800
(5) Required only if series F or later, 1.0 space factor or larger Bulletin 2100 unit is installed in topmost location of series A through E vertical sections.
(6) Consult MCC Technical Support at 1-800-646-5800 for assistance with possible door hinge requirements.
(7) Series E-J sections cannot accommodate 0.5 space factor units in bottom-most unit location.
(8) A ground strap can be used to ground units rather then installing a ground bus. See publication 2100-IN014x-EN-P.

Receiving, Handling and
Storage
Receiving
As standard, CENTERLINE Motor Control Centers are shipped upright in
shipping blocks of one to three front-mounted sections or two to six
back-to-back sections. Each shipping block of an MCC is provided with a
lifting angle. The lifting angle is optional on NEMA Type 3R and Type 4
MCCs. Each vertical section in a shipping block is bolted to the shipping skid
and covered with clear plastic wrap. Equipment that extends from the
structures is also protected. Protection is for upright shipping and is not
waterproof or watertight. If necessary, other types of packaging are available.
Refer to publication 2100-IN040x-EN-P for receiving, handling and storage
instructions. This publication is shipped with each MCC, attached to the
outside of the MCC within the layer of clear plastic wrap. For additional
information about the handling, installation, operation and maintenance of
motor control centers rated more then not 600 volts, consult
NEMA ICS 2.3-1995.
Export Packaging
A maximum of three vertical sections standing upright can be shipped with
export packaging together in one block. The motor control center is bolted to
a skid and wrapped in poly wrap suitable for occasional water-spray; a wooden
frame and chipboard surround the sections. Export packaging is not
watertight, waterproof or intended for long-term storage. Extended storage
may require space heaters and other considerations. Export packing adds extra
weight and dimensions to the shipping block.

Handling
Lifting with a forklift, overhead lifting, sling lifting and pipe or rod rolling are
methods that can be used to handle vertical sections. See Table 1.E and Table
1.F for typical weights and dimensions for standard 20” (508mm) wide and
15” (381 mm) or 20” (508mm) deep sections.
For sizes not listed consult your local Rockwell Automation Sales Office.

1-12 General Information
Storage
CENTERLINE MCCs conform to NEMA standard ICS-18-2001 for service
and storage conditions. All MCCs should operate in an ambient temperature
above 32oF (0oC) but not exceeding 104oF (40oC) at 95% non-condensing
humidity. If the equipment is stored, the ambient temperature should remain
above -22oF (-30oC) but not exceed 149oF (65oC). In addition, MCCs have an
altitude class of 2 km. The altitude class of 2 km designates equipment for
installation where the altitude does not exceed 2000 meters (6600 feet).
ATTENTION Motor control centers are top and front heavy. To avoid
personal injury or structural damage, never attempt to lift
or move the motor control center by any means other than
the methods outlined in publication 2100-IN040x-EN-P,
Receiving, Handling and Storing Motor Control Centers.
