RCBO, or Residual Current Circuit Breaker with Overcurrent Protection, is an automatic electrical switch designed to protect circuits from overload, short circuits, and earth fault. It is a combination of an MCB (Miniature Circuit Breaker) and an RCCB (Residual Current Circuit Breaker). The primary purpose of an RCBO is to ensure the safe operation of electrical circuits by triggering disconnection whenever an imbalance is detected. It offers combined protection against overloading, short-circuiting, and earth faults.

The RCBO is a current sensing component that can automatically disconnect and measure the circuit whenever the current exceeds the rated sensitivity, or a fault occurs in a connected circuit. This device helps protect against electrical shocks, fires, and electrocution, as well as assisting in sudden earth faults.
