The Milesight CT310 measures current on all three phases of a supply up to 1000 A per phase. The three split-core clamps fit around existing cables without de-energising the board, so it suits distribution boards, plant, chillers, compressors and production lines.
Why pick it
- Samples at up to 3.3 kHz and reports RMS and accumulated current, with optional accumulated energy, at ±1%.
- Powers itself from the monitored cable (phase A), so there is no battery to change. Below 10 A it needs 5 V over USB-C.
- Threshold and over-range alarms, an optional NTC probe for cable temperature, and firmware updates over the air.
IP30, indoor use. Approvals: CE, FCC and UL508.
Works with any standard LoRaWAN gateway and network server, such as the Milesight UG65 indoors or the UG67 outdoors, with alerts and dashboards on IoT Factory.
The CT3xx family also includes the CT303 (300 A). For single-circuit monitoring see the Milesight CT101.
