Littelfuse Introduces Its Residual Current Monitor Product Line for Electrical Charging Stations
Littelfuse introduces Western Automation's Residual Current Monitor product line, detecting ground fault currents in EV charging installations for sustainable, connected, and safer driving.
When a residual fault current occurs, the RCM sends an output signal that triggers a relay or contactor to shut off the supply power and remove the shock hazard during electrical vehicle charging. 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,” stated Philippe Di Fulvio, Littelfuse EV Infrastructure Business Development Manager. “The RCM monitor detects AC and DC ground fault currents and quickly triggers a fault output to disable the charging current and remove the shock hazard when charging vehicles.”
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.
