This 30A circuit breaker uniquely combines the functions of a resettable 30A fuse and an On/Off switch in one unit. It is suitable for a wide range of DC system voltages - from 12V to 48V. Designed to protect the system from over-current as a result of high power draw, short-circuits, wiring mistakes, equipment faults or any other high current event. The circuit breaker is resettable and has a manual-break option which allows it to be used as an isolator On/Off switch. Made from strong thermal plastic engineered to withstand high temperatures (UL94V-0 rated). It is also water resistant (IP67 rated) and ignition protected.
