200A 12V/24V/48V automatic over-current DC circuit breaker

This 200A circuit breaker combines the functions of a resettable 200A fuse. It is perfect for any DC system that requires over-current protection and is suitable for a wide range of DC system voltages from 12V to 48V.

Similar to a 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 circuit breaker is made from strong thermal plastic designed to withstand high temperatures (UL94V-0 rated). Additionally, it is water-resistant (IP67 rated) and ignition-protected (meets international standards S.A.E. J1625, J1171, UL1500).

This product is suitable for various 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.
