R718N37
For three-phase circuits up to 75 A per phase, the R718N37 uses three split-core clamp CTs that snap around existing conductors, so it can be retrofitted to a live installation without disconnecting anything. Current is reported over LoRaWAN with better than ±1% accuracy from 300 mA to 75 A. The main unit is battery powered (two AA-size lithium cells, around five years at 15-minute reporting), rated IP53 and mounts by screw or magnet; the R718N37E version has detachable CT cables for easier routing. Building owners use it to track individual three-phase loads, detect stalled or overloaded equipment, and allocate consumption across tenants or departments.

Requires a LoRaWAN Gateway
R718N37 sends its data over LoRaWAN, so it needs a LoRaWAN Gateway in range. Works with any LoRaWAN Gateway, such as the UG65. If you already have a Gateway on site, you can skip this.
