The WPEVCU40BSP/8 is an 8 Way IP65 EV Connection Unit with Surge Protection designed for higher-load EV charger installations requiring dependable isolation and transient voltage protection. Built to order and supplied preassembled, it combines a 100A main switch isolator, 40A MCB, and Type 2 SPD within a compact, IP65-rated enclosure for quick, compliant installation.
Installer Tip: The 40A variant is ideal for EV chargers drawing up to 9.6kW or for circuits with higher diversity factors. Maintain short SPD earth connections (under 150mm) to comply with BS 7671 surge protection requirements and minimise let-through voltage.
- 100A main switch isolator for safe disconnection and maintenance
- 40A B-Curve MCB – overload and short-circuit protection for high-demand EV chargers
- Factory-fitted Type 2 SPD – protects connected equipment from transient overvoltage
- IP65 weatherproof enclosure – suitable for external mounting
- Fully preassembled for fast, regulation-compliant installation
- Complies with BS EN 61439-3 and 18th Edition surge protection rules
- Built to order – typically dispatched within 3 working days
| Model | MCB Rating | Main Switch | SPD Type | Ingress Rating | Common Use |
|---|---|---|---|---|---|
| WPEVCU32BSP/8 | 32A | 100A Isolator | Type 2 SPD | IP65 | Single EV charger (≤7.4kW) |
| WPEVCU40BSP/8 | 40A | 100A Isolator | Type 2 SPD | IP65 | High-load EV charger (≤9.6kW) |
This 40A configuration provides additional headroom for faster chargers or circuits under heavier load. Built in compliance with BS 7671 Amendment 2, it’s suitable for PME and TT systems when paired with a PME Fault Detection Unit or upstream Type A RCBO.
Is this suitable for outdoor EV charger installations?
Yes. The IP65-rated plastic enclosure is designed for external mounting, offering full protection against dust and water ingress.
Does it include surge protection?
Yes – a Type 2 SPD is factory-fitted to protect EV circuits from transient overvoltage. For three-phase chargers, see our 3 Phase SPD Enclosure.
Is this 18th Edition compliant?
Yes. Fully compliant with BS 7671:2018 Amendment 2, including isolation and surge protection requirements for EV supply equipment.
Does it include PEN fault protection?
No – this model provides overload and surge protection only. For PME or TT systems requiring PEN protection, use with a PME Fault Detection Unit.
What size EV charger is it suitable for?
The 40A MCB suits EV chargers drawing up to approximately 9.6kW, depending on the manufacturer’s specifications.
