Commercial RCD devices that keep your installation safe.

Commercial RCD devices play a vital role in keeping larger electrical installations safe, protecting both people and equipment from the dangers of earth faults and leakage currents. A residual current device works by constantly monitoring the flow of electricity and cutting the supply instantly if it detects an imbalance, helping to prevent electric shocks and reduce the risk of fire.

Our range of commercial RCD devices is designed for use in distribution boards across offices, retail units, industrial premises, and other demanding environments. Built to meet the rigorous standards expected on professional sites, these devices offer reliable performance, robust construction, and dependable protection day after day.

Whether you are fitting out a new commercial project or upgrading an existing system, you will find trusted brands and a variety of ratings to suit your requirements. Browse the full selection below and choose the right level of protection for your installation.
