Structure
The CENTERLINE 2100 Motor Control Centers structure consists of sections, wireways, doors and
plug-in or frame mount units. CENTERLINE 2100 MCCs are listed by UL as complying with MCC
Standard UL 845.
Sections
The rigid, free-standing sections are assembled individually. Shipping blocks are factory assembled
from individual sections. Multiple section shipping blocks have continuous lifting angles, horizontal
power bars, horizontal ground bus and internal mounting angle.
Fault containment is enhanced with two side sheets on every section. This helps prevent a single fault
from cascading throughout the structure, limiting equipment damage.
The regid design or CENTERLINE 2100 MCCs helps ensure a longer life in all applications. Plug-in units
can still be installed and removed and doors closed securely after years of dependable service.
Mounting Configurations
The MCC is available in two mounting configurations – front mounted and
back-to-back mounted.
• Front mounted sections are joined and installed side-by-side.
• Back-to-back mounted sections are two separate sections joined at the rear.
The two sections have separate power bus systems providing the same
phasing for all units. The horizontal power bus is linked, front to rear, with a
factory installed U-shaped bus splice assembly.
Back-to-back vertical sections are made up of two separate vertical sections.
The front and back sections have separate horizontal and vertical power bus
providing the same phasing on units, both front and back. Full usage of unit
space is available for front and back section. There is no back plate between
the sections.
