RCM-EV-03 Residual Current Monitoring Device

  • Direct to cable or PCB mounting
  • For Mode 2 and Mode 3
  • Compliant with IEC 62752
  • Fixed 6mA DC and 30mA trip levels
  • Two independent switching outputs
  • 13.5mm cable aperture

A PCB-mounted residual current monitor for Mode 2 and Mode 3 EV charging equipment, detecting both 6 mA smooth DC and 30 mA AC residual currents. Separate switching outputs and a proportional PWM output provide flexible integration with charger control electronics.

  • Auxiliary supply: 5–12 V DC
  • Monitored circuit: 230/400 V AC, 32 A, 50/60 Hz
  • Residual current trip level: 6 mA DC / 30 mA AC (fixed)
  • Application: Mode 2 and Mode 3 EV charging
  • Outputs: Separate 6 mA, 30 mA and error open-collector outputs; PWM output
  • Mounting: Direct PCB mounting
  • Dimensions (mm): W:42.5 × H:46 × D:27
  • Product standards: IEC 62752; conditional IEC 62955

Typical applications include:

  • Portable Mode 2 EV chargers
  • Residential Mode 3 wallboxes
  • Public AC charging stations
  • Workplace AC charging points

Key benefits:

  • Supports a controlled fault response — Detection of 6 mA smooth DC and 30 mA AC 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.
