Resettable circuit breaker / switch for DC systems to protect against over-current.  30A/40A/50A/60A/80A/100A/120A/150A/180A/250A
 
This circuit breaker combines functions of a resettable fuse and On/Off switch in one unit. It is ideal for any DC system that requires both over-current 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 over-current 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;
Between off-grid inverter DC input and batteries;
DC power distribution or charging circuits;
Other DC automotive and marine applications.
