Residual Current Device (RCDs)

MK Circuit Protection range of RCDs offer a comprehensive selection of devices designed to meet most residential, commercial and light industrial requirements.

The range is a two and four pole, a.c. sensitive and d.c. sensitive devices with a selection of current ratings from 25A to 100A and is available in 30mA, 100mA and 300mA tripping sensitivities.

When in the OFF position a contact gap of 4mm is present, enabling MK Sentry RCDs to be used as isolating switches where appropriate.

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’. It is not possible to hold the contacts closed when a fault condition exists.

All MK Sentry RCDs incorporate a filtering device to provide protection against transient surges in the supply to the unit, thus reducing the occurrence of unwanted tripping.
