Acrel ASJ series residual current relays are mainly suitable for TT or TN system distribution lines with AC 50Hz and rated voltage of 400V and below. They are equipped with low-voltage circuit breakers or low-voltage contactors to reduce electrical safety accidents caused by leakage and ensure the safety of staff.
