ASJ series relays can be combined with low-voltage circuit breakers or low-voltage contactors to form a combined residual current action protector. It is mainly suitable for TT or TN system distribution lines with AC 50Hz and rated voltage of 400V and below to prevent damage caused by ground fault current. Equipment and electrical fire accidents, and can also be used to provide indirect contact protection against personal electrical shock hazards.
