ASJ20-LD1C Residual Current Relay

● The measurement of A-type after-current;

● The streamer display of current percentage;

● The setting of rated residual action current;

● The setting of non-driving time of limitation;

● Two-pair relay output;

● Possessing the function of on-the-spot and long-distance testing and resetting.


General

ASJ series residual current action relay can be combined with low voltage circuit breaker or low voltage contactor to form a combined residual current protection device. It is mainly used for TT and TN system distribution lines with AC 50Hz and rated voltage of 400V and below.
