Overview
The GE 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 family of products is versatile with
fuse and circuit breaker options, internal or
external DC return bars, 800A, 28-position
panels and a VIM1 smart meter to monitor
voltage and current of each load bus.

On Time Delivery

Fuse / Circuit Breaker Panels
Distribution panels have 28 bullet-style positions
that accept either TPS or TPL fuses up to 125A
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.

Cabinet Options
The cabinet for the BDFB / BDCBB is
7ft, seismic zone 4 rated, with up to six
28-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.
1, 2 and 4 ½ foot tall cabinet extensions are
available for various cable rack heights.

VIM 1 Intelligent Meter

Total Efficiency

The VIM1 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 VIM1 receives
redundant power from
Load A and B buses
as well as an optional
external Auxiliary Battery
Supply (ABS) connection.

The GE Total Efficiency™ (TE) architecture
reduces energy loss and lowers cooling
costs by 50-70%. TE products will prioritize
sustainable energy sources like solar, wind,
water and fuel cells over traditional utility grid
or diesel generator sources – and they will
intelligently respond to smart grid information
to reduce consumption during peak demand
periods. Active Rectifier Management (ARM)
and Battery Charging Optimization (BCO)
features increase efficiency on current and
legacy power infrastructures. The Total
Efficiency architecture addresses issues endto-end based on our proven experience and
expertise in batteries, power distribution, DC
energy systems, AC-DC power supplies, and
DC-DC board mounted power to deliver a
solution that is more safe, reliable and energy
efficient than competitive alternatives.
