2u dc distribution panel

Product Information

DPP2U Series 2u dc distribution panels provide distribution and overload protection for 1 to 20 circuits with circuit breakers that can be field installed/exchanged using a supplied puller tool.

UNIPOWER’s DPP2U Series circuit breaker panels provide distribution and overload protection for 1 to 20 circuits with circuit breakers that can be field installed/exchanged using a supplied puller tool. The panels are only two mounting positions (3.5 inches) high.

The dual-bus model provides up to 20 breakers 900A (10A/10B) distribution and alarm capabilities. The A and B sections are fully isolated from each other and are polarity neutral. Breaker capacities range from 2.5 to 200 amperes. A single-bus 450A model is also available.

Breaker and power fail alarms are indicated by a dual color LED (green/red) and Form C relay contacts for each bus.

Rear accessed load cables connect via 2-hole anti-rotation posts. All connections are straight on for easy installation.

THREE YEAR WARRANTY

Breakers need to be ordered individually and are shipped with each panel as separate items for field installation.

Breakers rated 125A to 200A require two positions and are supplied as a kit with output bus paralleling bars.
See datasheet for installation restrictions.

See datasheet for details of the approved types of breakers.
