2U DC Breaker 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
