A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overcurrent, typically resulting from overload or a short circuit. Its basic function is to interrupt current flow after a fault is detected.
Normal Operation: Electricity flows through the circuit breaker uninterrupted.
Fault Occurs (e.g., overload or short circuit): The breaker detects the fault via thermal or magnetic mechanisms.
Trip Mechanism Activates: The breaker "trips," opening the circuit and stopping the current flow.
Manual Reset Required: After the fault is cleared, the breaker must be manually reset to restore power.
No. 88, Changxing Street, Luolong District, Luoyang City, Henan Province
