Earth leakage circuit breaker An Earth leakage circuit breaker (ELCB) is a safety device used in electrical installations with high Earth impedance to prevent shock. It detects small stray voltages on the metal enclosures of electrical equipment, and interrupts the circuit if a dangerous voltage is detected. Circuit breaker A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit.Its basic function is to interrupt current flow after a fault is detected. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume ... MOULDED CASE CIRCUIT BREAKERS, EARTH LEAKAGE CIRCUIT ... 3 Any electric work must be carried out by a qualified person (electrician). Before wiring, turn off the upper circuit breaker and make sure of no current conducting. Electrification can result.
