The WEVKIT63 is a pre-built EV protection kit featuring a 63A B-Type RCD and a 40A Type C MCB - designed to meet the latest EV charger requirements, including protection against smooth DC earth leakage. It's a ready-to-fit solution for installers working with Tesla chargers and other EV brands where Type A RCDs are not suitable.
By combining a B-Type RCD with a high-inrush MCB, this kit helps ensure safe, regulation-compliant installs for both domestic and commercial EV charge points.
- Includes: 63A 4-Pole B-Type RCD + 40A Type C MCB
- DC Earth Leakage Protection: Detects smooth and pulsating DC faults
- Overcurrent Protection: MCB provides 40A C Curve protection
- Ideal For: Tesla wall connectors and EV chargers requiring Type B RCD
- Compact Size: 110mm (W) × 175mm (H) × 91mm (D)
- Fully pre-assembled: Quick-fit board for EV installs
Why do some EV chargers need a B-Type RCD?
B-Type RCDs detect smooth DC leakage - a requirement for certain EV charge points (including Tesla wall connectors) that can bypass Type A protection.
Is this kit compliant with 18th Edition regulations?
Yes - this kit meets BS EN 61008 and satisfies DC leakage protection requirements for EV charging circuits.
Can I use this with a Tesla wall charger?
Yes - this unit is specifically recommended for Tesla EV charger installs that specify B-Type RCD protection.
What’s the difference between a Type A and Type B RCD?
Type A RCDs detect AC + pulsating DC faults. Type B RCDs detect all of those plus smooth DC — which is crucial for EV charging stations using non-isolated inverters.
Does this come in an IP-rated enclosure?
No - this version is supplied in a standard enclosure. If you need IP65, contact us for alternative models.
