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)
