Chint Type A residual current circuit breaker with integrated overcurrent protection

This model successfully replaces two separate devices – a residual current device (RCD) and a miniature circuit breaker (MCB) – thereby saving valuable space in the distribution board and simplifying installation work.

The device provides comprehensive 3-level protection: it protects people from electric shock in case of accidental contact with live parts, protects buildings from fire hazards caused by current leakage, and protects the electrical installation itself and connected appliances from short circuits or overloads. The CHINT NB310L/3N is ideal for three-phase consumers such as heat pumps, electric vehicle charging stations, electric stoves, motors, or commercial electrical inlets.
