Residual Current Circuit Breaker with Over Current Protection RCBO/RCCB
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.

Applications and Markets
- Residential Buildings: RCBOs are used in homes to protect circuits supplying power to areas where there is an increased risk of electric shock, such as bathrooms, kitchens, and outdoor circuits.
- Commercial Buildings: In commercial environments like offices, retail stores, and restaurants, RCBOs can protect circuits that supply power to appliances, lighting, and other equipment, ensuring the safety of occupants and property.
- Industrial Facilities: In industrial settings, RCBOs can be used to protect sensitive equipment, control panels, and machinery from electrical faults, minimizing downtime and damage.
- Medical Facilities: RCBOs are particularly important in hospitals, clinics, and other medical facilities, where they protect patients, staff, and medical equipment from electrical hazards.
- Educational Institutions: RCBOs are used in schools, colleges, and universities to protect students, staff, and electrical equipment from electrical faults and accidents.
