Product Benefits :
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.
