Publication 2364F-5.01– October 2003
1-22 Overview
RGU Standard Features RGU standard features include:
Electrical System Features
• A 3-phase circuit breaker / motor circuit protector rated for
65kAIC:
•J, K, and L-code units have motor circuit protectors
•M-code units have circuit breakers
•N-code units have circuit breakers for control power with
motor-operated circuit breakers carrying rated bridge
current
• AC line, current-limiting fuses rated at 600V AC with short
circuit protection rated at 65kAIC
• AC line reactors in a quantity of 1 per phase
• A "basic capacity" control power transformer that supplies ONLY
the RGU with single-phase, 115V AC control power
• Primary and secondary control transformer fusing (excluding the
control bus fuse that is supplied with the "6P" control power
source upgrade option)
• A "DC-Bus-Energized" pilot light that turns on when the bus
voltage is above 50V DC
• A DC bus suppressor module
• Utilization of #16AWG or #14AWG MTW (PVC insulated)
rated, stranded copper control wiring
Packaging Features
• The Bulletin 2100 CENTERLINE motor control center (MCC)
packaging makes the RGU compatible with other Bulletin 2100
and 2300 products
• Unit depth of 20" (J, K, L-code RGUs), overall unit depth of 25”
(M and N-code RGUs)
• Ability to connect to other common DC bus MCC sections on
both the right and left sides
• Top-entry AC line input
• Removable top-plate for cutting conduit holes
• Easy accessibility for routine maintenance
