Residual Current Devices – RCDs

Ultimate protection of people and equipment

Residual Current Devices (RCDs) are the safest device to detect and trip against electrical leakage currents, thus ensuring protection against electric shock caused by indirect contacts. These devices must be used in series with a Miniature Circuit Breaker (MCB) or fuse which protects them from the potentially damaging thermal and dynamic stresses of any overcurrent. They also act as the main disconnecting switches upstream of any derived MCBs (e.g., domestic consumer unit).
