IP65 Metal EV Consumer Unit – RCBO, MCB & Surge Protection

This pre-fitted single-phase IP65 metal consumer unit comes ready-wired with a 40A C curve RCBO and Type 2 surge protection device, designed for EV charger installations where all the protection needs to be in a single, tough, weatherproof enclosure. It reduces installation time by arriving fully assembled — the installer simply mounts it, makes the incoming and outgoing connections, and the board is ready. Choose between RCBO + SPD or Main Switch + RCBO + SPD. Pre-wired and ready to connect. All components are factory-fitted in a lockable, non-combustible aluminium enclosure with an IP65 rating, suitable for garages, workshops and outdoor EV charger installs. Does not include PEN fault detection. If the installation is on a PME supply, a separate PEN fault detection device is required under BS 7671. See our combined PEN fault + surge unit for the all-in-one PME solution.

It means the RCBO and surge protection device are already installed and wired inside the enclosure when it arrives. The installer does not need to fit individual components — they simply mount the board, connect the incoming supply, and connect the outgoing circuit to the EV charger. This saves time on site, particularly when installing multiple units. Which configuration should I choose? Choose RCBO + SPD for a straightforward EV charger circuit. Choose Main Switch + RCBO + SPD if you also want a 100A main switch to isolate the whole board in one operation, which makes testing and maintenance simpler. Does this include PEN fault detection? No. This board provides RCBO and surge protection only. For a PME supply, you also need PEN fault detection — either a separate module or the combined PEN fault + surge unit which includes all three functions in one enclosure. What type and rating of RCBO is included? A 40 A Type A RCBO with C curve. Type A detects AC and pulsating DC earth leakage, with 6mA DC protection. The twin-handle design shows the cause of a trip: if only the black handle trips, it indicates overload or short circuit; if both the black and white handles trip, it indicates a residual current fault. How do I know when the surge protection needs replacing? The Type 2 SPD has a visual indicator. Green means good, red means replace the module. Is this suitable for a domestic installation? Yes. This unit is designed primarily for domestic single-phase EV charger installs, and the metal IP65 enclosure suits outdoor and garage locations. It can also be used on light commercial installs with a single-phase supply. For 3-phase or commercial multi-charger applications, see our 3-phase range.
