RCBO

A Residual current circuit breaker with over-current protection (RCBO) is a critical safety measure when protecting electrical circuits. 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 happens in a connected circuit.
This device is purposed to protect one from the risk of electrical shocks, firesand electrocution. It can also assist in sudden earth faults. The installation of an RCBO ensures that a circuit trips immediately and protects you from electric shock.
