DC Power Systems & Inverters



The GE/ABB Battery Distribution Fuse Bay (BDFB) or Battery Distribution Circuit Breaker Bay (BDCBB) serves as a secondary power distribution unit for -48V DC power from the battery plant to the load equipment. The H569-445 24” deep distribution bay is versatile with fuse and circuit breaker options, internal or external DC return bars, 800A, 20 position panels, and a VIM1 smart meter to monitor voltage and current of each load bus.

Cabinet Options

Cabinets are 7’ tall, 24” deep with a width option of 30” or 34”. Each cabinet can have up to 8 20-position distribution panels. Each panel may be individually fed with an 800A load bus or multiple panels may be joined together. Load bus assemblies include a 1500A shunt and landings for four 750kcmil cables. Factory supplied shunt wiring to each panel allows cabinets to be transitioned into different load configurations in minutes for maximum flexibility.

Fuse / Circuit
Breaker Panels

Distribution panels have 20 bullet style positions that accept holders for TPS fuses up to 70amps, TLS fuses up to 125 amps, or circuit breakers up to 250A. Any fuse or circuit breaker may be installed in any position with no spacing requirements. Each panel includes its own alarm lights for power loss and fuse/breaker alarms. Hinged doors on each panel provide circuit breaker and fuse protection and prevent incorrect installation.

VIM1EC Intelligent Meter

The VIM1EC smart meter monitors voltage and current of each load center with individually configured overload thresholds, power loss, and fuse/breaker alarms. Form-C relays for each of the three alarms are accessed via terminal blocks located at the top of the cabinet. The VIM1EC receives redundant power from Load A and B buses as well as an optional external Auxiliary Battery Supply (ABS) connection. The VIM1EC provides the ability to monitor the BDCBB over intranet or internet if connected to a GE Galaxy Millennium 2 or Pulsar Plus Controller using GE’s proprietary GP protocol. With the addition of the Pulsar Gateway feature, the BDCBB can be monitored independently. The Network Gateway feature allows monitoring of up to (16) BDCBBs.
