RCM-EV-06 Residual Current Monitoring Device

  • Low profile – PCB mounting
  • Compliant with IEC 62955
  • Fixed 6mA DC trip level
  • For Mode 3 applications
  • Single switching output
  • 13.5mm cable aperture

A low-profile 6 mA DC residual current monitor for Mode 3 EV charging equipment. Designed for direct PCB mounting, it provides a switching output, error output and proportional PWM signal for monitoring and control.

  • Auxiliary supply: 5–12 V DC
  • Monitored circuit: 230/400 V AC, 32 A, 50/60 Hz
  • Residual current trip level: 6 mA DC (fixed)
  • Application: Mode 3 EV charging
  • Outputs: 6 mA and error open-collector outputs; PWM output
  • Mounting: Low-profile PCB mounting
  • Dimensions (mm): W:34 × H:20 × D:49
  • Product standard: IEC 62955

Typical applications include:

  • Residential Mode 3 wallboxes
  • Workplace AC charging points
  • Public AC charging stations
  • Fleet depot AC charging

Key benefits:

  • Supports a controlled fault response — Detection of 6 mA smooth DC residual currents provides a signal that the charging controller can use to command external disconnection of the affected charging circuit.
  • Supports integration into charger electronics — Direct PCB mounting places the residual-current sensor within the charging electronics assembly, helping designers incorporate monitoring into the charger control layout.
  • Provides additional monitoring information — A proportional PWM signal allows the charging electronics to monitor smooth DC residual current alongside the switching outputs.
  • Supports functional verification — The documented test input allows the charger electronics to initiate a test of the monitoring function during equipment verification or a system-controlled test sequence.
