Description
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.

FAQs
What’s the difference between Type B and Type C RCBO curves?
Type C RCBOs tolerate higher inrush currents before tripping, making them ideal for EV chargers with transformer or inverter-based designs.
Is this unit compatible with PME fault detection?
Yes. It can be used as part of a PME-compliant installation when paired with a PEN fault detection device.
Does it include surge protection?
No. Surge protection can be added separately at the supply board if required.
Is it pre-wired?
No. The RCBO is supplied fitted but un-wired, allowing the installer to configure the final connections.
Is this suitable for domestic EV chargers?
Yes. It’s ideal for 32 A single-phase chargers, particularly those with higher startup currents.
