Circuit Breaker Panels Feature Up To 300A

Distribution and overload protection from one to 12 dc circuits is provided with the new DPB1U circuit breaker panels, which mount only 1.75” high. The panels provide one to six single bus breakers or two to 12 dual bus breakers. They distribute up to a total of 300A load current from two separate 150A sources with true A and B distribution and also come equipped with alarm capabilities. The A and B sections of the panel are isolated and can be configured for handling 12, 24 or 48 Vdc, positive or negative ground. Circuit breakers are available from 1 to 50A. A circuit breaker alarm is indicated by a dual color LED for each bus and two Form C relay contacts per bus. A fail-safe option lets the A and B sides operate redundantly from two separate feeds. The panels are 1.75” high, 19” wide and 9” deep and come with brackets that permit mounting in either 19” or 23” relay rack. The DPB1U series is priced as low as $231 each in quantity.
