A-Type RCBO EV Kit – 2 Way 40 A C Curve (WMEV240C)

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.

• 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)

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.

• Add SPD protection upstream if required by design or manufacturer

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.
