R718NL363
Aimed at main incomers and large plant, the R718NL363 monitors three-phase current from 10 A up to 630 A per phase using split-core clamp CTs, and adds an ambient light sensor spanning 0.01 to 157,000 lux in the same LoRaWAN device. Current accuracy is within ±1% with 1 mA resolution. The battery-powered main unit (two AA-size lithium cells, around five years at 30-minute reporting) is rated IP53 and fixes by screw or magnet; the CTs are rated IP30 and open around existing cables so installation needs no downtime. Applications include monitoring high-current supplies to buildings, thermal systems and machinery, while the light channel shows whether plant-room lighting is left on.
