    This circuit breaker is a 150A 12V/24V/48V automatic over-current DC circuit breaker/switch that combines the functions of a resettable 150A fuse and an On/Off switch in one unit. It is suitable for any DC system that requires over-current protection and manual isolation of the circuit. The breaker is compatible with 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. However, unlike fuses, this circuit breaker is resettable and does not require replacement when blown. Additionally, it has a manual-break option, allowing it to be used as an isolator On/Off switch for simple disconnection and reconnection of the system.

    The circuit breaker is made from strong thermal plastic (UL94V-0 rated) and is designed to withstand high temperatures. It is also 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 inputs and batteries, DC power distribution or charging circuits, and other DC automotive and marine applications.
