  • 1. Brief introduction

    ES210T is Single Phase Din-rail multifunctional smart sensor. It also functions as a fire detector. This smart sensor is composed of safety monitoring unit and metering unit with RS485 communication function. The built-in current transformer is used to monitor the remaining current, and the built-in temperature sensor is used to monitor the wire temperature.


    The smart sensor has buzzar alarms when over-heating or overload. 3 LED indicators are available for showing relay on-off, load situation and operation status.
