The WMEV332C is a compact 3-way EV RCBO enclosure engineered for earth leakage and overload protection on single-phase EV charging circuits. Supplied with a 32A Type A High Immunity RCBO (Type C curve), it provides dependable 30mA AC and 6mA DC leakage protection, ensuring compliance with BS 7671:2018 Amendment 2.

This Type C version is designed for EV chargers with higher inrush currents — typically those using switched-mode power supplies or onboard transformers. Its compact metal body and EV-specific protection make it an excellent choice for residential and light commercial installs requiring 6mA DC detection and reliable disconnection performance.

Installer Tip: Type C curves are best suited for EV chargers with higher start-up or transformer inrush currents. Always verify the charger specification to avoid nuisance tripping.
