This 180A circuit breaker combines the functions of a resettable 180A fuse and an on/off switch in one unit. It is ideal for any DC system that requires both over-current protection and manual isolation of the circuit. 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 resulting from high power draw, short-circuits, wiring mistakes, equipment faults, or any other high current event. The circuit breaker is resettable, making it a superior alternative to fuses that require replacement when blown.

The breaker also has a manual-break option, allowing it to be used as an isolator On/Off switch for simple disconnection and reconnection of the system. Made from strong thermal plastic engineered to withstand high temperatures (UL94V-0 rated), the breaker is also water-resistant (IP67 rated) and ignition protected, meeting international standards S.A.E. J1625, J1171, UL1500. This product is suitable for a wide range of DC applications, including connecting solar or wind charge controllers to batteries, between off-grid inverter DC input and batteries, DC power distribution or charging circuits, and other DC automotive and marine applications.
