NEW PRODUCT! Series 53 Battery switch circuit breaker

MP Series 53

Battery Switch Circuit Breaker

MP Series 53
Branch Disconnect Circuit Breaker

The MP Series 53 is designed specifically to bring together two traditionally separated products (breaker / switch) into a single small package device that may be conveniently located for ease of access. The MP Series 53 combines key attributes required of ABYC circuit breakers (UL1077 & SAE J1428) and the Marine Power switching standards (UL1107). This new innovative product provides upstream backup short circuit protection up to 3,000 amperes for the branch house circuits.  This device helps prevent battery draw down while the switch is in the off position while providing savings in space, labor, and wiring costs.
