Description

The Milesight CT310 is a LoRaWAN® Smart Current Transformer for energy monitoring in heavy industrial and utility-scale facilities. With a 1000A rated primary current per CT, the CT310 uses induced current power technology to run by harvesting energy directly from the Phase A conductor. No external wiring or batteries are needed, and the non-invasive split-core design installs without de-energizing the equipment.

Core Capabilities

Energy-Harvesting Runs on induced current from the measured conductor, so there is no battery to replace.
High-Resolution Metrics 3.3 kHz sampling frequency and ±1% measurement accuracy for RMS current tracking.
NTC Temperature Support Works with an external NTC sensor to monitor conductor temperature from -20°C to 100°C.
3-Phase Detection Simultaneous 3-phase detection with large 51mm wire-hole clamps for main electrical feeds.

Energy Management Use Cases

• Sub-metering: Monitor main distribution boards in large commercial centers or industrial parks.
• Machine Health: Detect electrical anomalies in large motors or industrial furnaces before they fail.
• Peak Load Analytics: Profile consumption patterns and find inefficiencies in large electrical systems over LoRaWAN.

Technical Integration

The CT310 is compliant with LoRaWAN® Class A and is available for the EU868, US915, AU915 and other frequency bands. It supports Firmware Update Over-the-Air (FUOTA) and threshold alarms for immediate notification of electrical excursions. When harvesting power from Phase A, the unit needs a minimum primary current (60A at 1-minute reporting or 35A at 10-minute reporting). For low-current sites or initial setup, the unit can be powered via its USB Type-C port. Contact the shopioT engineering team for system architecture support.
