What power supply do I need for an electric industrial roller shutter door?
The power supply required for an electric roller shutter door will depend mainly on the size, weight and expected frequency of use of the door. Smaller or medium‑sized shutters, especially on lighter‑duty openings, can often be operated from a single‑phase 230V supply using a suitably rated motor and control panel. Larger industrial doors, high‑use shutters on loading bays or car parks, and doors carrying heavier insulated or wind‑rated curtains will usually need a three‑phase 400V supply to ensure reliable lifting, smoother operation and reduced strain on the motor over time. During the survey stage our engineers will confirm what is already available on site and what will be required for the recommended specification. If power is not yet present at the opening, we can liaise with your electrical contractor to identify the correct cable sizes, isolation requirements and control positions so everything is ready when the door is installed.
