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.

Air circulation
When two poles are placed adjacent to each other, these channels form a tunnel resulting in effective air circulation around individual poles
Bi-connect Termination Possible
Choice to use Busbar and/or cable in the same terminal,provides reliable termination
Din Rail Mounting
Two step snapping mechanism for easy & efficient mountion in 35mm DIN Rail steadily
