ASJ20-LD1C Residual Current Relay

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.

Feature

• The measurement of AC-type residual current;

• Indicator of current off-limit alarm;

• 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
