The WMEV240C is a 2-way A-Type RCBO EV Kit fitted with a 40 A C-curve high-immunity Type A RCBO. It provides combined overload, short-circuit and earth-leakage protection (30 mA AC + 6 mA DC) and meets the latest 18th Edition Amendment 2 requirements for EV installations.
Designed for high-load single-phase chargers or dual EV points (up to ≈ 9 kW), the C-curve profile (5–10 × In) withstands inrush currents from transformer or switch-mode power supplies without nuisance tripping. Each unit is factory-wired and ready to install with dual-pole isolation and clear fault indication.
Installer Tip: Use the 40 A C-curve for high-power chargers or paired EV sockets drawing up to ≈ 9 kW. If the charger specifies Type B RCD requirements, install with a PME fault unit and surge protection for full compliance.
- 40 A C-curve Type A RCBO (30 mA AC + 6 mA DC detection)
- Dual-pole (1P + N) isolation for safe disconnection
- Compact 2-way steel enclosure with hinged cover
- High-immunity design prevents false trips on EV loads
- Complies with BS EN 61009-1 and BS 7671 (A2)
| Part Code | Rating | Curve | Typical Use |
|---|---|---|---|
| WMEV232C | 32 A | C | 7 kW chargers / standard domestic circuits |
| WMEV240C | 40 A | C | High-load or dual-socket EV installations |
Each kit is pre-built and ready for install. For PEN-fault and load-balancing compliance, pair with our PME Fault Detection Unit. Add a Single Module SPD for surge defence if required.
When should I choose the 40 A C Curve version?
Use it for high-load or dual-socket EV chargers drawing up to ≈ 9 kW where startup inrush current may trip lower rated devices.
Is this kit 18th Edition compliant?
Yes – it includes a Type A RCBO with 30 mA AC + 6 mA DC detection as required by Amendment 2.
Does it isolate both live and neutral?
Yes – the 1P + N RCBO provides full dual-pole isolation for safe maintenance and fault clearance.
Can I add surge protection?
Yes – fit a Single Module SPD or an upstream surge unit as required by specification.
Is it suitable for PV as well as EV circuits?
Yes – the Type A RCBO is bi-directional and approved for EV and solar PV applications.
