The WEVCU32BSP is a fully pre-wired EV connection unit combining surge protection, overload protection, and isolation inside a compact 5-module IP40-rated metal enclosure. Fitted with a 100A double-pole main switch, Type 2 SPD, and 32A MCB, it provides a ready-to-fit solution for EV charge point installations requiring 32A protection under BS 7671:2018 Amendment 2.
This model is ideal for single-phase EV chargers rated up to 7.4kW, providing a clean and compliant means of isolation and protection in line with 18th Edition requirements. The integrated SPD safeguards both the charger and supply from transient voltage spikes, helping prevent nuisance tripping and damage.
Installer Tip: Position this unit close to the charge point and keep the SPD earth lead as short as possible to reduce impedance and maintain surge protection effectiveness.
- Pre-wired 5-module metal consumer unit – quick to install
- 100A double-pole main switch for full isolation
- Type 2 SPD included for transient overvoltage protection
- 32A MCB (C Curve) for overcurrent and short-circuit protection
- Ideal for single-phase 7.4kW EV chargers
- Surface-mount IP40 steel enclosure for indoor use
- Compatible with TN-S and TT earthing systems

The WEVCU32BSP gives installers a fast, all-in-one solution for EV charge point protection. By combining the main switch, MCB, and SPD in one compact board, it simplifies compliance with 18th Edition EV circuit requirements and reduces time on site.
Does the WEVCU32BSP include a surge device?
Yes. It’s fitted with a Type 2 SPD to protect the EV charger and circuit from transient overvoltage events.
Do I still need an external isolator?
No. The 100A double-pole main switch provides local isolation in line with BS 7671 requirements.
Can it be used outside?
No. The unit is IP40 rated for indoor installations only.
Is it ready to use out of the box?
Yes. It’s fully pre-wired — simply connect the supply and load conductors and test before energising.
Is it suitable for 7kW EV chargers?
Yes. The 32A MCB suits most single-phase EV chargers rated around 7.2–7.4kW.
