EV Connection Unit – 100A Main Switch + SPD + 32A B Curve MCB (WEVCU32BSP)

The WEVCU32BSP is an EV connection unit with a 32A B Curve MCB, 100A main switch and surge protection device (SPD) in an IP40 metal enclosure. It combines overcurrent protection, switching and surge protection for the charge-point supply.

This is the MCB connection-unit configuration. The MCB provides overload and short-circuit protection; the required residual-current, smooth-DC and any open-PEN protection must be addressed by the complete charger and circuit design.

Please contact Power & Data UK for the exact supplied SPD classification, performance values and assembly installation data where these are needed for the circuit design.

A qualified electrician must select, install and test the WEVCU32BSP using the supplied assembly instructions and EV charger requirements.

• Check that the 32A B Curve MCB suits the load, cable and required disconnection performance.
• Confirm the residual-current and DC-fault protection required for the charger supply, and assess the earthing arrangement and any open-PEN protection.
• Use this IP40 metal version in a suitable dry indoor location.
• Follow the supplied wiring diagram, SPD coordination, conductor and terminal-torque instructions.
• Complete inspection, testing and labelling before putting the circuit into service.

Which MCB curve is supplied?

WCED lists a 32A B Curve MCB for WEVCU32BSP.

Does the 100A main switch make this a 100A charger supply?

No. The main-switch rating and MCB rating describe different components. This configuration contains a 32A MCB; the permitted circuit load depends on the complete design.

Does this provide the same protection as an RCBO kit?

The listed components are a main switch, MCB and SPD. An MCB does not provide the residual-current function of an RCBO. Confirm the charger's built-in protection and the additional protection required for the circuit.

Is it suitable for outdoor mounting?

This is the IP40 metal version for dry indoor use. Compare WPEVCU32BSP for an IP65 plastic enclosure.

Which surge protection device is fitted?

WCED confirms an SPD in this configuration. Please contact Power & Data UK for its exact model, classification and performance values if these determine your selection.
