The WCED EV Connection Unit is a compact 3-way IP40 metal enclosure designed for safe isolation and circuit protection of electric vehicle (EV) charging points. It comes factory-fitted with a 100A double-pole main switch for isolation, alongside your choice of 32A or 40A MCB to protect against overload and short-circuit faults.
This unit is commonly used where a simple, cost-effective connection point is needed for EV sockets and chargers. It ensures compliance with 18th Edition Amendment 2 and is compatible with further protection devices such as RCBOs where required.
Available configurations:
- WEVCU – 100A Main Switch + 32A MCB
- WEVCU32B – 100A Main Switch + 32A Type B MCB
- WEVCU32C – 100A Main Switch + 32A Type C MCB
- WEVCU40B – 100A Main Switch + 40A Type B MCB
Each version allows you to match breaker size and curve type to the EV charger’s demand profile — whether a 32A single-phase charger on a Type B breaker, or a slightly heavier 40A charger requiring extra capacity.
Dimensions: 110mm (H) x 175mm (W) x 91mm (D)
If you require additional protection, see our IP65 EV Connection Unit for outdoor use, or the surge-protected version for compliance with the latest EV charging regulations.

Does this unit include surge protection?
This 3-way model does not include an SPD. For EV installs requiring surge protection, choose the 5-module EV Connection Unit with SPD.
Is it RCBO compatible?
Yes – while supplied with a main switch and MCB, the unit is RCBO-ready if additional earth leakage protection is required.
What sizes of MCB are available?
Options include 32A (Type A, B, or C curve) and 40A (Type B) to suit different charger ratings.
