This circuit breaker combines the functions of a resettable 40A fuse and an on/off switch in one unit. It is an ideal solution for any DC system that requires both overcurrent protection and manual isolation of the circuit. The breaker can be used with a wide range of DC system voltages from 12V to 48V.
The circuit breaker is designed to protect the system from overcurrent resulting from high power draw, short circuits, wiring mistakes, equipment faults, or any other high current event. Unlike fuses that require replacement when blown, the circuit breaker is resettable, making it a better alternative.
Furthermore, the breaker has a manual-break option, allowing it to be used as an isolator on/off switch for easy disconnection and reconnection of the system.
The circuit breaker is made from strong thermal plastic engineered to withstand high temperatures (UL94V-0 rated). It is also water-resistant (IP67 rated) and ignition-protected (complies with international standards S.A.E. J1625, J1171, UL1500).
This product is suitable for a variety 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, and other DC automotive and marine applications.
It's important to note that this product is suitable for panel or recess mount.
