30A DC Circuit Breaker — 12V/24V/48V

30A 12V/24V/48V Automatic over-current DC circuit breaker / switch This 30A circuit breaker combines functions of a resettable 30A 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?ÿas 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?ÿignition 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.
