Product Detail

Parameter

General

ASJ series residual current operated relay can be combined with low voltage circuit breaker or low voltage contactor to form a residual current protection device, which is mainly used for the TT and TN system distribution lines with AC 50Hz and rated voltage of 400V and below. It is used to protect the electrical circuit form ground faults, prevent equipment damage caused by earth fault current and electrical fire accidents, and can also be used to provide indirect contact protection against personal electric shock hazard.
