Product Description

 Residual Current Circuit Breaker with Over Current Protection RCBO/RCCB

 

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.

Over-Current Protection

Similar to an MCB, an RCBO also offers protection against overloads and short circuits. Overloads occur when too much current flows through a circuit, usually due to too many devices being connected or a malfunctioning device. Short circuits happen when the live and neutral wires come into direct contact, resulting in an extremely high current flow. In both cases, the RCBO will trip and disconnect the circuit to prevent damage to electrical equipment, wiring, and reduce the risk of fire.

Combined Protection

By integrating both residual current and over-current protection in a single device, an RCBO provides comprehensive protection for electrical circuits, enhancing safety and reducing the need for separate RCDs and MCBs.

Easy Reset

Once the cause of the trip has been identified and resolved, the RCBO can be easily reset, restoring power to the circuit.

ESRO1-50 RCBO Residual Current AC Breaker with Overcurrent Protection 1P+N

Product Benefits :

• The current steadily rises to the specified value within 5s
• Pole No. to  1P+N
• Rated voltage to 240V~
• Tripping curve B C D

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.
