250A 12V/24V/48V Automatic over-current DC circuit breaker

This 250A circuit breaker functions as a resettable 250A fuse. It is suitable for any DC system in need of over-current protection, and can be used with a wide range of DC system voltages from 12V to 48V. As with any fuse, the circuit breaker is designed to safeguard the system from over-current events caused by high power draw, short-circuits, wiring errors, equipment faults, or any other occurrence of high current. The circuit breaker is resettable, making it a more convenient option than fuses, which require replacement when blown. Constructed from durable thermal plastic, it can withstand high temperatures (UL94V-0 rated), and is also water-resistant (IP67 rated) and ignition-protected (meets international standards S.A.E. J1625, J1171, UL1500). This product is suitable for a variety of DC applications, including use between off-grid inverter DC input and batteries, in DC power distribution or charging circuits, and in other automotive and marine DC applications.
