CT3xx
Three-phase smart current transformer
The CT3xx series from Milesight is designed for three-phase energy monitoring (1 to 3 phases). Its innovative 'One-to-Three' design enables monitoring of up to three circuits with a single LoRaWAN module. Self-powered with a 3.3 kHz sampling rate, these sensors deliver real-time RMS measurements and cumulative amp-hours. They include threshold and overcurrent alerts for predictive maintenance. Non-invasive clip installation without cutting power.
