Product Details
MD0630T41A is an AC DC leakage current sensor for electrical safety. It has the characteristics of high sensitivity, correct measurement, small size and compact/integration design. The residual current monitor can be set separately for AC and DC leakage. When leakage current is detected, an alarm signal is generated, and the switch control signal is output at the same time.
MD0630T41A is a differential current (DI) sensor specifically developed for EV-charging, providing all-current sensitivity. The residual current detector can output signal in case of hazardous electrical faults (DC and AC) according to IEC 62752 IEC 62955 or UL2231. It is a residual current monitor intended for the detection of DC and AC residual currents in 50Hz/60Hz AC installations. The RCM is connected in series with the AC supply to an EV and will provide a signal output if a DC current ≥ 6mA DC flows in the circuit. It will protect against DC (6mA) and AC (30mA) residual currents, and will signal to the Smart EVSE if a fault occurs. It would be required to guarantee safety in the event of DC fault current. It is especially suitable for electric vehicles charging, residential charging, commercial charging, public charging various public places.

MD series RCD/RCM sensor are compact, molded-type, sensitive and lightweight zero phase current transformers. They are ideal for improving electric shock prevention, which are used where DC residual currents could occur, in addition to normal AC, can detect high-frequency AC and pure DC earth leakage currents. The tripping conditions are defined with different frequencies from 50Hz to 1kHz. Reducing the risk of fire or electrocution through output digital alarm signal. Typical applications include electric shock prevention from earth leakage breakers, short-circuit relays, and ground fault circuit interrupters, photovoltaic systems, electric vehicle charging stations and medical equipment etc.
