Issue 4 January 1999 Product Description 2 - 1
2 Product Description
Overview
The J85568E-1 Mini-Distribution Bay (Power Distribution Bay)
distributes -48Vdc power in a two-load arrangement, with a
300-ampere capacity per load. There are four fuse or circuit
breaker panel positions. Load Bus A connects the top two fuse
or circuit breaker panels. Load Bus B connects the bottom two
fuse or circuit breaker panels. All panel positions must be
equipped with either a fuse or circuit breaker panel or a blank
panel. Each fuse panel is equipped with twelve fuse blocks for
0-60A fuses. Each circuit breaker panel has 12 empty positions
for up to 12 circuit breakers.
This Mini-Distribution Bay is designed to mount in a 23-inch
relay rack. See Figure 2-1. It can also be factory installed in an
ED8C800-50
7
′
framework. See Figure 2-2. If the Mini-Distribution Bay is
installed in a 7
′
framework that will be located in a 9
′
or 11
′
-6
″
environment, bay extenders are available. Ordering information
for the extenders is given in Section 3. Note: Do not mount
Mini-Distribution Bay onto bay extenders. Other equipment
can be added to this framework, which saves valuable floor
space.
The Mini-Distribution Bay offers the same fusing and alarm
monitoring features as the J85568C-series distribution bay, but
in a more compact design. It provides another Lucent
Technologies alternative to secondary distribution requirements.
