63A 100mA RCD 2 module
An RCCB provides protection against earth faults occurring in equipment and reduces the effects of electrical shock on human beings and thus saves lives.
An RCCB measures the current flowing in the live and neutral cables and if there is an imbalance, that is current flowing to earth above the RCCB sensitivity, the RCCB will trip and cut off the supply.
All Contactum RCCBs incorporate a filtering device to provide protection against transient surges in the supply to the unit, thus reducing the occurrence of unwanted tripping.
Contactum RCCBs must never be used as the sole method of direct contact protection, but are invaluable in providing supplementary protection where damage may occur.
When in the OFF position a contact gap of 4mm is present, enabling Contactum RCCBs to be used isolating switches where appropriate.
