What is an RCCB circuit breaker?

An RCCB, or residual current circuit breaker, is an electrical wiring device that will break the circuit once it detects that the current leaks to the ground wire. It is also referred to as an RCD (residual current device) or RCB (residual current circuit breaker).

What is an RCBO circuit breaker?

An RCBO circuit breaker, or Residual Current Circuit Breaker with Overload Protection, combines the functions of a Miniature Circuit Breaker (MCB) and a Residual Current Device (RCD)/Residual Current Circuit Breaker (RCCB). When there is current leakage, the RCBO trips the entire circuit. Therefore, when the circuit is overloaded, the internal magnetic/thermal circuit breaker element will trip the electronic device.

What are RCDs and circuit breakers?

RCD or Residual Current Devices, also known as Safety switches, and Circuit Breakers are essential safety devices for electrical systems. They protect from electrocution and fire hazards caused by electrical faults when properly installed.

What does a circuit breaker do?

Circuit breakers perform 3 key functions: protection, switching, and monitoring. Circuit breakers are designed to “break” (discontinue) the flow of electricity to protect people and equipment when current reaches an unsafe level due to overload, short circuit, or other electrical faults.
