Product Details

MD0630T41A is an AC DC leakage sensor (residual current sensor) for EV charging station. It has the characteristics of high sensitivity, correct measurement, small size and integration. The residual current monitor can be set separately for AC and DC leakage. The MD0630T41A residual current monitor is intended for the detection of DC and/or AC residual currents in AC or DC installations. The RCM is ideally suited for use with Electric Vehicle charging cables (Mode 2 Protection) and EV charging stations (Mode 3 Protection), and for fault current monitoring and electrical safety on electric vehicle charger.

When the set current is reached, an alarm signal is generated, and the switch control signal is output at the same time. MD series leakage detection sensor is a differential current (DI) sensor specifically developed for EV-charging providing all-current sensitivity. The sensor can output signal in case of hazardous electrical faults (DC and AC) according to IEC 62955, IEC 62752 or UL2231. Type B RCD/RCM is an ideal protection device, for the detection of different leakage currents in applications of DC screen, Fire distribution cabinet, PV inverters, medical equipment, UPS devices, EV charging facilities etc.
