Product introduction:
RCMX-100 residual current monitor (leakage relay ），monitoring the effective value of residual current (maximum 30A/2KHz) together with independent residual current transformer (CT). When the residual current exceeds 50% of the action value, the pre-alarm relay acts. The shell is gray flame-retardant polycarbonate Lexan UL94 VO, and the residual current measurement range is 0-30A (15Hz-2KHz), with the help of external CT action value connected with terminals 8 and 9. User programmable double relay output (can be set to positive safety or negative safety and early warning mode)
