RCD's Residual Current Device Offers Protection against Electric Shock
An RCD provides protection against earth faults occurring in equipment and reduces the effects of electric shock on human beings and thus saves lives.
An RCD measures the current flowing in the live and neutral cables and if there is an imbalance, that is current flowing to earth above the RCD sensitivity, the RCD will trip and cut off the supply
All Contactum RCDs incorporate a filtering device to provide protection against transient surges in the supply to the unit, thus reducing the occurrence of unwanted tripping.
- Contactum RCDs must never be used as the sole method of direct contact protection, but are invaluable in providing supplementary protection in high risk environments where damage may occur.
When in the OFF position a contact gap of 4 mm is present, enabling Contactum RCDs to be used as isolating switches where appropriate
