Protect your wind turbine, battery bank and alternative energy system from over-current or short circuit damage. This Auto Reset Circuit Breaker is a Single Pole (Type 1) breaker. The metallic material inside the circuit breaker allows electricity to flow as long as the current stays under 50 amps. If the current exceeds 50 amps, the metallic material inside the breaker begins to heat up and deflect. This deflection breaks continuity inside the circuit breaker and electricity stops flowing. The circuit breaker will remain disconnected until the current drops below 50 amps. Once the current drops below 50 amps, the metallic material inside the circuit breaker cools, continuity is restored and electricity starts to flow again.
