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.

The 2u dc distribution panels are only two mounting positions (3.5 inches) high. Standard models provide up to 20 breakers dual-bus 900A (10A/10B) distribution and alarm capabilities.

The A and B sections of the dual-bus 2u dc distribution panels are fully isolated, can be separately configured for 12 or 24/48 volts and are polarity neutral. Breaker capacities range from 2.5 to 200 amperes. Optional single-bus 450A models are 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.

DPP2U Series 2U dc distribution panels meet the requirements of NEBS GB-1098-CORE and GR-63-CORE.

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.
