The Milesight CT103-868M is a LoRaWAN® smart current transformer for remote energy monitoring, rated up to 250 A. It shares the compact detachable split-core body of the CT101 (Ø16 mm wire hole) and installs safely without de-energizing circuits.
It is self-powered by the induced current in the monitored wire, requiring no batteries or external power. An optional NTC temperature probe connects via USB-C. Configuration is via USB-C or downlink.
Before you install
- Setup: over USB-C or a LoRaWAN downlink, no app.
