The WPEVCU32BSP is a compact IP65 EV connection unit pre-fitted with a 32A B Curve MCB, 100A isolator, and Type 2 Surge Protection Device (SPD). Designed for domestic EV charger installations, it provides weatherproof circuit protection that complies fully with BS 7671:2018 (Amendment 2).
This ready-to-install unit combines overload protection, circuit isolation, and surge defence in a single enclosure — making it ideal for EV supply points, solar PV inverters, or external distribution circuits where resilience and compliance are essential.
Installer Tip: Use the 32A B Curve variant for standard single EV charger installs on domestic supplies. The B curve handles domestic load profiles without nuisance tripping, while the SPD safeguards against overvoltages.
