RCM-EV-02/S Residual Current Monitoring Device

  • Direct to cable
  • Compliant with IEC 62955
  • Fixed 6mA DC trip level
  • For Mode 3 applications
  • Single switching output
  • 13.5mm cable aperture

A compact 6 mA DC residual current monitor for Mode 3 EV charging equipment. The /S variant is designed for direct attachment to the monitored cable and provides a single open-collector fault output to support controlled disconnection by the charging system.

  • 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: Single open-collector fault output
  • Mounting: Cable mounting; rear right-angle latching connector
  • Dimensions (mm): W:42.5 × H:46 × D:27
  • Product standard: IEC 62955

Typical applications include:

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

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.
  • Simplifies cable-based installation — Direct attachment to the monitored cable and a rear latching connector allow the sensor to be positioned around the cable and connected to the charger electronics.
  • Avoids local threshold setup — The fixed 6 mA DC threshold removes the need to adjust a local DC trip setting during assembly, helping keep the specified detection threshold consistent.
  • 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.
