For the first time since we have owned the boat (28 years), we have more power than we need. Fantastic, and thanks again.

This 120A circuit breaker combines functions of a resettable 120A fuse and on/off switch in one unit. It is ideal for any DC system that requires both overcurrent 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 overcurrent as a result of high power draw, short-circuits, wiring mistakes, equipment faults or any other high current event. The circuit breaker is resettable which makes it a superior alternative to fuses which require replacement when blown.

Additionally, 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 circuit breaker is made from strong thermal plastic engineered to withstand high temperatures (UL94V-0 rated). The breaker is also 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 including:

  • Connecting solar or wind charge controllers to batteries;
  • Sitting between off-grid inverter DC input and batteries;
  • DC power distribution or charging circuits;
  • Other DC automotive and marine applications.


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