Residual Current Relay

Residual current relay series products are used in ground fault protection of circuits to prevent electrical equipment damage and fire accidents caused by equipment ground fault current, and can also provide indirect contact protection against electric shock hazards. The relay can form a combined freewheeling generating device, which is mainly used for TT and TN system power distribution circuits of 50Hz alternating current.Residual Current Relay series is very easy to use with on-site and remote test reset functions.
