ASJ60-LD16A Residual Current Monitor
● Monitoring and display residual current of TN-S,TT distribution lines;
●16 measuring channels per devices for residual current measurement;
●Adjustable alarm value with ranges: 1mA…30A;
●1 relay for waterlog, 16 relays for 16 channels residual current monitor
●2 DI for waterlog and other switch status;
ASJ60-LD16A residual current monitor is suitable for distribution lines of 400V a.c. and below, to monitoring residual current as a residual current electrical fire monitoring detector, or combined with low-voltage circuit breaker or AC contactor to be residual current devices to protect the electrical circuit from ground fault. Prevent equipment damage and electrical fire accident caused by ground fault current, or provide indirect contact protection against personal electric shock. ASJ60-LD16A can be used in distribution boxes of petrochemical, industrial plants, large public buildings, kindergartens, nursing homes and other places, as well as in distribution boxes of street lamps, courtyard lamps and landscape lamps for leakage or grounding fault monitoring.
