The WMEV220C is a 2-way A-Type RCBO EV Kit fitted with a 20 A C-curve high-immunity Type A RCBO. It delivers combined overload, short-circuit and earth-leakage protection (30 mA AC + 6 mA DC) and meets 18th Edition Amendment 2 standards for EV circuits. Suited to 4–5 kW single-phase chargers...
The WMEV220C is a 2-way A-Type RCBO EV Kit fitted with a 20 A C-curve high-immunity Type A RCBO. It delivers combined overload, short-circuit and earth-leakage protection (30 mA AC + 6 mA DC) and meets 18th Edition Amendment 2 standards for EV circuits.
Suited to 4–5 kW single-phase chargers with inrush or transformer input, the C-curve tripping profile (5–10 × In) prevents nuisance tripping while ensuring fast fault disconnection. It arrives pre-assembled in a durable 2-way steel enclosure with full dual-pole isolation and clear fault indication.
Installer Tip: Select the 20 A C-curve for 4–5 kW chargers or commercial feeds with mild inrush. For purely resistive loads, use a B-curve version; for larger units, step up to 25 A or 32 A.
- 20 A C-curve Type A RCBO (30 mA AC + 6 mA DC detection)
- Dual-pole (1P + N) isolation – disconnects live and neutral
- Compact 2-way steel enclosure with hinged cover
- High-immunity design reduces false trips on EV loads
- Complies with BS EN 61009-1 and BS 7671 (A2)
| Part Code | Rating | Curve | Typical Use |
|---|---|---|---|
| WMEV216C | 16 A | C | 3.6 kW chargers with transformer input |
| WMEV220C | 20 A | C | 4–5 kW EV chargers / small commercial feeds |
| WMEV225C | 25 A | C | 5–6 kW chargers / light commercial applications |
Each kit is pre-built and ready to install for rapid, compliant EV protection. 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 20 A C Curve version?
Use this variant for 4–5 kW chargers or light commercial EV circuits with moderate inrush current.
Is this kit compliant for EV installations?
Yes – it includes a Type A RCBO with 30 mA AC + 6 mA DC detection to 18th Edition Amendment 2.
Does it switch both live and neutral?
Yes – the 1P + N RCBO provides complete dual-pole isolation for safety and maintenance.
Can I add surge protection?
Yes – fit a Single Module SPD or an upstream surge unit as required by spec.
Is it suitable for solar PV as well as EV?
Yes – the Type A RCBO is bi-directional and approved for both EV and PV systems.
