Key Points

FAQ

Both parallel arcs and series arcs are detected, which covers hazards such as ageing wiring and poor contact in final circuits.
Overvoltage 200~300V, undervoltage 100~187V, overcurrent 5~63A and arc count 2~30 are all adjustable. Factory settings are 260V, 160V, 32A and 10 respectively.
An arc produces a local sound and light alarm with an LCD indication, and the alarm is uploaded to the monitoring platform over RS485 at 9600bps. The event is also written to the log, which keeps the most recent 5000 records.
The detector mounts on a 35mm DIN rail inside the distribution enclosure. It monitors loads of AC63A and below, equivalent to circuits of 10kW and below.
Certification is held through a CE / CMA / CNAS accredited laboratory. Price is quoted per unit and quantity; Request a quote with the model code and the protection settings required.
