This 250A circuit breaker acts as a resettable 250A fuse . It is ideal for any DC system that requires over-current protection. The breaker is suitable for a wide range of DC system voltages from 12V to 48V. Like any fuse, this circuit breaker is 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 which makes it a superior alternative to fuses which require replacement when blown. The circuit breaker is made from strong thermal plastic engineered to withstand high temperatures (UL94V-0 rated). The breaker is also water resistant (IP67 rated) and ignition protected (meets international standards S.A.E. J1625, J1171, UL1500). This product is suitable for a wide range of DC applications including: Between off-grid inverter DC input and batteries; DC power distribution or charging circuits; Other DC automotive and marine applications.
