The WMRC40BSP metal EV consumer unit brings a 40A B curve Type A RCBO and Type 2 surge protection together in a compact indoor enclosure. It gives installers a clearly specified protection assembly for an EV charger circuit, with twin-handle fault indication to help make subsequent fault finding easier.
Why choose the WMRC40BSP?
- Protection supplied together: the RCBO combines overload, short-circuit and 30mA residual-current protection, while the SPD addresses transient overvoltages.
- Easier fault identification: the RCBO’s separate MCB and RCD handles help an electrician distinguish an overcurrent trip from a residual-current fault.
- Compact indoor fit: the IP40 metal enclosure measures 110 × 175 × 91mm (W × H × D), useful where wall space is limited.
- Practical cable access: top and bottom 25/32mm knockouts support cable routing into the enclosure.
Check the charger specification
Choose this model where the circuit design specifies 40A B curve overcurrent protection and Type A residual-current protection. B curve describes the overcurrent characteristic; it does not mean Type B RCD protection. Confirm the charger’s DC residual-current and open-PEN protection arrangements separately before ordering.
