Residual Current Breaker with Over-Current protection (RCBO) is a safety device used in electrical systems that combines the functions of a Residual Current Device (RCD) and a Mini Circuit Breaker (MCB). An RCBO is designed to protect both people and equipment by detecting residual currents (leakage currents) and over-currents (overloads and short circuits). It is commonly used in residential, commercial, and industrial applications to enhance the safety and reliability of electrical installations.
Residual Current Protection
An RCBO constantly monitors the current flowing through the live (hot) and neutral wires of a circuit. Under normal conditions, the current flowing in both wires should be equal. However, if there is a leakage current (e.g., due to a faulty appliance or current flowing to the ground through a person), the RCBO detects the imbalance and trips, disconnecting the circuit to prevent electric shock.

Residual current-operated circuit breakers (RCBO)with overcurrent protection are mainly suitable for applications that require both overcurrent protection (overload and short circuit)and ground-fault current protection. It can detect faults and trip in time to ensure the safety of staff and equipment. Can be applied to energy management systems, power supply, and distribution network automation, residential power monitoring, and complete sets of equipment.
