Residual current relay is a device that detects the leakage currents that occur during the operation of the electrical circuit and thus prevents the negative consequences that may arise. Leakage currents leaking from the electrical circuit can cause problems such as fire, electric shock, relays are therefore very important devices.
Residual current relay is a type of circuit breaker that is automatically activated in case of leakage current in electrical systems. Leakage current is dangerous for both people and devices. Relays, which are a precaution against leakage current, cut the circuit and the power supply to the load when they detect such a situation. This device is used to prevent damage to people or equipment.
