Product Description
50 Amp Branch Disconnect Circuit Breaker
1/4″ -28 Stud Terminals
Traditional battery disconnect switching and circuit protection in a single device. Made in the USA!
The Series 53 Branch Disconnect/Circuit Breaker incorporates traditional battery disconnect switching (non-engine) and circuit protection into a single rotary switch, eliminating the need for a separate battery switch and circuit breaker/fuse. The Series 53 provides a quick means to disconnect traditional downstream circuits while preventing unintentional battery drain or allowing for disconnected battery power during storage and maintenance.
