An RCD device complete with overcurrent protection is called an RCBO, or residual current circuit breaker with overcurrent protection.

The primary functions of RCBOs are to ensure protection against earth fault currents, overload, and short circuit currents.

An RCD provides additional protection against an electric shock. It works along side the circuit breakers for each circuit.

An RCBO provides the job of a circuit breaker and an RCD in one switch. This means that if a fault is detected, the individual circuit is 'tripped' and not a number of circuits.

 

The RCBO meaning is residual current circuit breaker with overcurrent protection. These devices are designed to ensure the safe operation of electrical circuits, triggering disconnection whenever an imbalance is detected.ontent or connect to a database.
