Chapter 1
System Overview
CENTERLINE® 2500 motor control centers (MCCs) are designed for
applications
that must comply with international standards and practices for
low-voltage motor
control centers. The CENTERLINE 2500 MCC is ideal for
tough
industrial applications where uptime and ease of maintenance is
required.
The CENTERLINE power bus structure distributes line power throughout the
MCC via an isolated bus work structure. A standard, center-fed,
300 A vertical bus supplies power to units above and below the horizontal bus,
which results in an effective 600 A capacity and unrestricted unit
arrangement. An optional 600 A vertical bus provides an effective rating of
1200 A.
ArcShield Rating The CENTERLINE MCC is also available with an ArcShield™ rating. This rating
includes arc-resistant features for enhanced protection if internal arcing faults
happen.
With the standard safety features of the CENTERLINE 2500 MCC, the
ArcShield option provides the following:
•Springlatches
• Reinforced structure
• Pressure relief vent system through the top of the enclosure
• Protection up 300 ms at 480V/65 kA
An ArcShield label is provided on the MCC with information about the
accessibility level and arc fault ratings. See Figure 8 on page 18 for an example
of this rating label and its location.
See Figure 4 on page 14 for the location of ArcShield structure protection and
page 54 for ArcShield door latches.

Protection Personal and assembly protection suitable for limited continued operation; assembly protection is
limited to outgoing units tested for conditional current under arcing conditions.
Requirements
Tested with third-party validation against the IEC/TR 61641 standard that defines tests under
conditions of arcing due to internal fault. Comprehensive tests conducted under Edition 3.0, 2014-1
have passed the requirements for Class A (meets Criteria1…5) for the main bus and unit line side,
and Class C (meets Criteria 1…7) for all unit load side tests.

Chapter 1 System Overview
Structure CENTERLINE 2500 MCCs offer units with a full complement of AC drives, soft
starters, and other devices. Pluggable power connections on the back of the
unit plug into the vertical bus. A mechanical interlock helps prevent the unit
door from being opened while the main switch is in the ON/I position. An
additional mechanical interlock helps prevent the unit from being withdrawn
or inserted when the unit main switch is closed. Separate vertical wireways
isolate control and network cables from power wiring. Units are available as
fixed or withdrawable.

Chapter 1 System Overview
Nameplate Data In compliance with EN 61439-1, each CENTERLINE 2500 MCC column is
supplied with a nameplate on the enclosure or vertical wireway door.
Figure 6 - Column Nameplate
Each unit also has an identification label. On withdrawable units, the unit
identification label is on the interior of the bottom plate of the unit. On fixed
units, the unit identification label is on the interior right side plate.
Figure 7 - Unit Identification Label
MCC Column-number
Sequence
Each CENTERLINE 2500 MCC column nameplate identifies column-number
sequence, for example, MCC column 1 of 1 or 1 of 5. See Figure 6 for where to
find column-number sequence information.
Columns are numbered to match factory-supplied MCC elevation drawings
and to identify MCC columns and units easily. If there are questions about
column numbering during field installation, inspection, or operation, the
following instructions can provide guidance.

The catalog number or serial number and series letter are required to identify the
equipment properly to sales or factory personnel.
IMPORTANT CENTERLINE 2500 MCCs are designed to function in any column-number
sequence. However, we recommend that columns be installed in
sequential order.
IMPORTANT Leftmost column must be installed in the proper location for the bus to
splice. (Both ends of double-front MCCs must be installed as ends for
splicing.)

Rockwell Automation Publication 2500-IN001F-EN-P - April 2021 17
Chapter 1 System Overview
The most important criteria for additions of columns to existing MCCs is
matching the horizontal bus, enclosure type, and network capabilities for the
complete MCC line up. The voltage, current rating, short circuit withstand,
and IP rating for all columns must be consistent.
ArcShield Labels MCC columns with arc proof assembly have a rating label (Detail E in Figure 8
on page 18) below the nameplate. There are also labels on other parts that must
be in place before operating an MCC with ArcShield; see Figure 8 on page 18.
At the end of a lineup, CENTERLINE 2500 MCCs with ArcShield have a back-
corner baffle and insulation on the center side closing-plate; see Figure 4 on
page 14 for more details. They also have external vertical support angles at each
end of the lineup.

Receiving, Handling, and Storage
See Receiving, Handling, and Storing CENTERLINE® 2500 Motor Control
Centers Instructions, publication 2500-IN002, for additional instructions.
This publication is shipped with each MCC, attached to the outside of the MCC
within the layer of clear polyethylene encasement (polywrap).
Receiving CENTERLINE 2500 MCCs are shipped upright as one or two column shipping
blocks or two or four double front column shipping blocks. Each CENTERLINE
2500 MCC shipping block is provided with a lifting angle. Each column in a
shipping block is bolted to the shipping skid with removable shipping angles
and covered with clear plastic wrap. Protection is for upright shipping and is
not waterproof or water-resistant. Equipment that extends from the
structures is also protected.
Heavy-duty export packaging is similar to standard packaging, but uses a
polywrap suitable for occasional water spray. In addition, wood framing and
sheeting surround the columns. The heavy-duty export packaging is not
water-resistant, waterproof, or intended for long-term storage.
Upon delivery of the MCC, see the packing slip shipped with your MCC for
sizes and exact shipping weights. Inspect the shipment for lost or damaged
items. If lost or damaged items are detected, see the steps that are described in
publication 2500-IN002.
Handling The following are acceptable methods of handling MCC columns within the
receiving facility. These methods are described in publication 2500-IN002.
• Use of a forklift
• Overhead lifting (crane or hoist)
• Sling lifting
MCC columns must be handled in the upright vertical position. Failure to
comply with this method can lead to busbar, unit, and enclosure damage.
ATTENTION: MCCs are top and front heavy. To avoid personal injury or
structural damage, lift or move the MCC by only the methods that are outlined in
Receiving, Handling, and Storing CENTERLINE 2500 Motor Control Centers,
publication 2500-IN002.

20 Rockwell Automation Publication 2500-IN001F-EN-P - April 2021
Chapter 2
The MCC must remain bolted to the shipping skid until delivered to its final
installation area.
Storage Store CENTERLINE 2500 MCCs, units, and related equipment in a clean, dry
environment with ambient temperatures ranging from -25…+55 °C
(-13…+131 °F).
For short periods (less than 24 hours), temperatures of up to 70 °C (158 °F) are
allowed. Take care to help prevent damage from exposure to excessive
humidity, vibration, and shock.
Store MCCs with the plastic covering in place to help prevent dirt and dust
from entering the structure. Check periodically for condensation build-up and,
if necessary, install space heaters. To order space heaters,
contact your
Rockwell Automation representative
.
ATTENTION: MCCs are top and front heavy. To avoid personal injury or
structural damage, never attempt to lift or move the MCC by any means other
than the methods outlined in Receiving, Handling, and Storing CENTERLINE 2500
Motor Control Centers, publication 2500-IN002.
