R718N363D Wireless 3-Phase Current Meter with 3 x 630A Clamp-On CT

   

R718N363D, the three-phase current meter, is to detect the current of three-phase load. The device is compatible with the LoRaWan protocol and equipped with a wireless communication module to display the collected data in the gateway. The R718N3xxD series is powered by DC and receives AC via current transformers (CTs), which proportionally convert high-voltage current in the primary winding into the lower-value current in the second winding.
