A-Type RCBO EV Kit – 2 Way 32 A B Curve (WMEV232B)

The WMEV232B is a 2-way A-Type RCBO EV Kit fitted with a 32 A B-curve high-immunity Type A RCBO. It provides overload, short-circuit and earth-leakage protection (30 mA AC + 6 mA DC) in full compliance with 18th Edition Amendment 2.

Ideal for 7.2 kW domestic EV chargers on dedicated radial circuits, this unit delivers robust protection and dual-pole isolation while maintaining compact installation dimensions. The high-immunity RCBO reduces false trips when charging vehicles with built-in filtering or variable current draw.

• 32 A B-curve Type A RCBO with 30 mA AC + 6 mA DC detection
• Dual-pole (1P + N) isolation – switches both conductors
• Pre-assembled in compact 2-way steel enclosure with hinged lid
• High-immunity design prevents nuisance trips with EV loads
• Complies with BS EN 61009-1 and BS 7671 (A2)

Each kit is pre-built and ready to install for fast, compliant EV protection. For PEN fault and load-balancing compliance, pair with our PME Fault Detection Unit. Add a Single Module SPD for surge protection if required by site specification.

Is this kit compliant for EV charger circuits?

Yes – it meets 18th Edition Amendment 2 with Type A RCBO (30 mA AC + 6 mA DC detection).

When should I choose the 32 A B Curve variant?

It’s the standard choice for 7 kW chargers on dedicated radial circuits fed from 32 A breakers.

Does it isolate both live and neutral?

Yes – the 1P + N RCBO provides complete dual-pole isolation for safe servicing.

Can I add surge protection?

Yes – pair with our Single Module SPD or install upstream surge units as required.

Is this kit suitable for PV systems as well as EV?

Yes – the Type A RCBO is bi-directional and safe for use with EV and solar PV circuits.
