1u front access dc breaker panel

Product Information

DPBF1U Series 1U front access DC breaker panels provide distribution and overload protection for 8 DC loads up to 30A.  The 1RU mounting position (1.75 inches) high DC breaker panels provide 8 single bus loads or 4/4 dual-bus (A&B) loads (up to 30A max. per load).

DPBF1U Series 1u front access dc breaker panels distribute up to a total of 150 amperes of load current from two separate 150A sources with true A and B distribution and alarm capabilities.  A and B sections of the dual-bus panel are isolated and can be separately configured for 12, 24/48 volts and are polarity neutral.

Breaker sizes are 1 to 30 amperes. Alarms are indicated by a Green/Red LED and one Form C relay contact per bus.

DPBF1U Series 1u front access dc breaker panels come with brackets that permit mounting in either a 19- or 23-inch relay rack.  They can be mounted from the front of the rack with offsets every quarter-inch from front to back to align with existing rack-mounted equipment.
