The WMEV216B is a 2-way A-Type RCBO EV Kit fitted with a 16 A B-curve high-immunity Type A RCBO. It provides overload, short-circuit and earth-leakage protection for EV charger circuits, detecting 30 mA AC + 6 mA DC fault currents to meet 18th Edition Amendment 2 requirements.
This variant is ideal for standard domestic single-phase EV chargers (up to 3.6 kW) where supply diversity and nuisance tripping must be minimised. It offers full dual-pole isolation and clear fault indication in a compact 2-way steel enclosure ready for fast fit-out and inspection.
Installer Tip: 16 A B-curve is the go-to choice for most 3.6 kW chargers. If your charger has a transformer or higher inrush current, switch to a C-curve version for extra surge tolerance.
- 16 A B-curve Type A RCBO (30 mA AC + 6 mA DC detection)
- Dual-pole (1P + N) isolation – disconnects live and neutral
- Pre-assembled in a compact 2-way steel enclosure
- Complies with BS EN 61009-1 and BS 7671 (A2)
- High-immunity design prevents false trips from EV charging loads
| Part Code | Rating | Curve | Typical Use |
|---|---|---|---|
| WMEV210B | 10 A | B | Small EV chargers / load-limited circuits |
| WMEV216B | 16 A | B | Standard 3.6 kW single-phase EV chargers |
| WMEV220B | 20 A | B | Heavier domestic or light commercial chargers |
Each kit arrives ready to install with a factory-fitted Type A RCBO and steel enclosure. For PEN fault compliance and load balancing, pair with our PME Fault Detection Unit. Add a Single Module SPD for surge defence where specified.
Is this kit compliant for EV charger circuits?
Yes – it includes a Type A RCBO with 30 mA AC + 6 mA DC detection as required by 18th Edition Amendment 2.
When should I use a 16 A B Curve model?
This is the recommended rating for most 3.6 kW chargers. For 7 kW chargers or units with transformers, choose a C-curve variant.
Does it isolate both live and neutral?
Yes – the 1P + N RCBO switches both conductors for full isolation and safety.
Can I add surge protection?
Yes – fit a Single Module SPD or upstream surge unit if required by site spec.
Is it suitable for PV as well as EV circuits?
Yes – the bi-directional Type A RCBO is safe for both EV and solar PV applications.
