• Protects against unwanted tripping

Sentry residential 230V Type AC 6kA residual current device (RCD) offer a high degree of protection against electrocution in accidental shock hazard situations. This two module RCD designed to meet most residential requirements. It is two pole A.C. fault current sensitive with a 40 amp current ratings and is available in a 30mA tripping current sensitivity. The operating dolly may be locked in either the On or Off position without affecting the ability of the trip mechanism to operate i.e. the RCD is ‘trip-free’. When in the off position a contact gap of 4 mm is present, enabling it is to be used as isolating switches where appropriate. It is not possible to hold the contacts closed when a fault condition exists. Positive indication of the opening of the contacts is only given when contact status indicator shows green. Incorporate a filtering device to provide protection against transient surges in the supply to the unit thus reducing the occurrence of unwanted tripping.
