BENDER RCM475LY-7113 residual current monitor with integrated CT, for TN/TT grounded AC system leakage monitoring.

Product Overview

BENDER RCM475LY-7113 is a residual current monitoring device from BENDER RCM475LY series. It is equipped with an integrated current transformer, used to detect AC and pulsating DC residual current in TN and TT grounded power systems. It continuously tracks leakage current, triggers alarm output once exceeding the preset threshold, helps find early insulation faults without immediate power cut. It can send alarm signals to PLC and DCS systems, widely used for electrical safety protection in industrial power distribution cabinets.

Key Features
