Details Additional Info Data Sheet Manual£98.42*
The Smart Current Transformer is a LoRaWAN®-enabled device with an innovative, non-intrusive quick installation. Suitable for 1 to 3 wires, it accurately estimates energy consumption with a sampling rate up to 3.3kHz and calculates cumulative ampere-hours every second, helping identify energy usage patterns for effective savings.
CT303 - With 300A Current Capacity
CT305 - With 500A Current Capacity
CT310 - With 1000A Current Capacity
With a one-to-three design, the current transformer can be applied to measuring up to three different objects' electricity. The user-friendly current clamp probe is designed for non-invasive and quick installation, eliminating the risk of circuit damage or power interruptions. Available in multiple wire hole sizes(24mm/36.6mm/51mm) to accommodate various wire thicknesses, ensuring broad compatibility across applications.
