MK Sentry 7880S 80A 30mA RCD 2 Pole

Residential 6kA Residual Current Devices (RCDs)

The Sentry range of RCD’s offer a comprehensive selection of devices designed
to meet most residential, Commercial and light industrial requirements.

The range is two pole, a.c. fault current sensitive with a
selection of current ratings from 16 to 80A and is available in a variety of tripping sensitivities.

When in the OFF position a contact gap of 4mm is present,
enabling Sentry RCD’s 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 Sentry RCD’s incorporate a filtering device to provide protection
against transient surges in the supply to the unit, thus reducing the occurrence of unwanted tripping
