The functions of automotive circuit breaker
1. Circuit breaker can do is protect the circuit from a high current short circuit.
2. Through its thermal trip it can protect the circuit from overload conditions. A circuit breaker will trip if too large a draw or current flow occurs across a thermal shunt inside.
3. It can also have a ground fault circuit interrupter integrated internally in case of a difference in potential between neutral and ground resulting from voltage leakage from appliances or to protect against potential electrocutions.
