Ground fault current detection for EV-Charging with the new Residual Current Monitor product line from Littelfuse

Electric-vehicle-charging

Littelfuse introduces its Western Automation Research and Development Residual Current Monitor (RCM) product line to detect AC and DC ground fault currents in electrical vehicle EV chargers. The RCM product line offers various models to support the global UL and IEC safety standards for EV charging applications. These products may be used to detect AC, DC, or both type of faults in single-phase or multi-phase installations.

Electrical vehicles are a major priority for car manufacturers, and it is only a matter of time before EVs become a significant proportion of all vehicles—making it paramount that charging applications are safe and reliable. The RCM monitor detects AC and DC ground fault currents and quickly triggers a fault output which immediately stops the charging and therefore removes the shock hazard from the charged vehicle. The Western Automation Research and Development Residual Current Monitor product line includes:

  • Multiple models to support global AC EV charger safety standards including:
    • Level 2 (UL2231-2)
    • Mode 2 (IEC62752)
    • Mode 3 (IEC62955)
  • Protection against both AC and DC leakage current that can present serious shock risks
  • Single-phase and three-phase designs in one component to simplify inventory
  • Chassis and board-level mounting options available for added flexibility
