General
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 cont actor 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.
Installation
Dimension
Typical Connection
Note:
1) Each residual current monitor can be configured with up to 16 AKH-0.66/L series residual current transformers to monitor the residual current of 16 circuits.
2) The L, N terminals of the residual current monitor are the auxiliary power supply terminals, which need to be connected with AC 220V, and the L terminal can be connected with 6A fuse in series as protection.
3) AKH-0.66/L series residual current transformer need to pass through L, N (single phase) or A, B, C, N (three-phase) lines of the circuit. PE wire does not need to pass through. The output line of residual current transformer is connected to the corresponding circuit terminal of residual current monitor. Unused channels must be closed in the menu to avoid false alarm.
4) A, B are communication terminals, when multiple residual current monitors are required to networked through RS485 bus, the communication terminals of each residual current monitor shall be connected hand in hand by 2×1.5mm2 shielded twisted pair. A matching resistor (120Ω) shall be connected in parallel between the two communication terminals of the two deviced at the end and head of the bus, to ensure normal communication.
