4 Pole, 40A 30mA RCCB (10kA) Orange is a type of electrical switch that provides protection against electric shocks and electrical fires caused by ground faults or leakage currents.
The RCCB constantly monitors the flow of current in an electrical circuit. It detects any imbalance between the current flowing into the circuit and the current returning from the circuit.
When the RCCB detects a significant residual current, it quickly interrupts the circuit by tripping, thereby cutting off the power supply. This action helps to prevent electrical accidents and potential damage to electrical equipment or wiring.
When an overload or short circuit occurs, causing the current to exceed the rated limit of the circuit, the circuit breaker will trip and interrupt the flow of electricity. This action shuts off power to the affected circuit, preventing further damage. Once the issue is resolved, the circuit breaker can be manually reset to restore power to the circuit.
