120A 12V/24V/48V AUTOMATIC OVER-CURRENT DC CIRCUIT BREAKER / SWITCH FOR PANEL OR RECESS MOUNT

This circuit breaker is a combination of a resettable 120A fuse and an on/off switch. It is perfect for any DC system that requires overcurrent protection and manual isolation of the circuit. The breaker is suitable for a wide range of DC system voltages, starting from 12V up to 48V.

The circuit breaker is designed to protect the system from overcurrent, caused by high power draw, short-circuits, wiring mistakes, equipment faults, or any other high current event. It is resettable, which makes it a better alternative to fuses, which need replacement when blown.

Moreover, the breaker has a manual-break option, which allows it to be used as an isolator on/off switch for simple disconnection and reconnection of the system. The breaker is made from strong thermal plastic engineered to withstand high temperatures (UL94V-0 rated). It is 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, such as connecting solar or wind charge controllers to batteries, sitting between an off-grid inverter DC input and batteries, DC power distribution or charging circuits, and other DC automotive and marine applications.

Please note that this product is suitable for panel or recess mount.
