RCM-EV-11 Residual Current Monitoring Device

  • Low profile – PCB mounting with integrated primary conductors
  • Compliant with IEC 62752 & UL 2231-2
  • Fixed 6mA DC and 20mA AC trip levels
  • Two independent switching outputs

A low-profile PCB-mounted residual current monitor with four integrated primary conductors, designed for Mode 2 EV charging equipment. It detects 6mA smooth DC and 20mA AC residual currents and provides separate switching outputs plus a proportional PWM output.

  • Auxiliary supply: 5 V DC
  • Monitored circuit: 230/400 V AC, 32 A, 50/60 Hz
  • Residual current trip level: 6 mA DC / 20 mA AC (fixed)
  • Application: Mode 2 EV charging
  • Outputs: Separate 6 mA, 20 mA and error open-collector outputs; PWM output
  • Dimensions(mm): W:34 × H:30 × D:49
  • Product standard(s): IEC 62752, partly combined with UL 2231-2

Typical applications include:

  • In-cable EV charging control boxes
  • Portable Mode 2 EV chargers
  • Fleet portable EV charging equipment
  • Travel EV charging equipment

Key benefits:

  • Supports a controlled fault response — Detection of 6 mA smooth DC and 20 mA AC residual currents provides a signal that the charging controller can use to command external disconnection of the affected charging circuit.
  • Simplifies PCB assembly — Four integrated primary conductors combine the monitored current path with the PCB-mounted sensor, reducing the need to route separate conductors through a sensor aperture.
  • 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.
