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.
- Supplied with 32A Type A High Immunity RCBO (C Curve)
- Detects AC, pulsating DC, and 6mA smooth DC leakage
- 3-module IP40 metal enclosure – compact and robust
- Dual overload and residual current protection
- PME-ready and compatible with surge protection devices
- Built to order – typically dispatched within 3 working days

The WMEV332C provides reliable EV circuit protection where Type C performance is preferred. With full 6mA DC leakage sensing and robust overload protection, it’s designed to keep modern EV charging systems safe and 18th Edition compliant.
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.
