Sentry Technical
Contactors
Description
Sentry contactors provide a method of remotely switching single and three phase loads. In this regard, they
are particularly useful for switching heating, lighting and ventilation circuits, in particular when used in
conjunction with REC supply off-peak tariffs.
They are suitable for mounting on a standard DIN rail and are therefore fully compatible with all Sentry
Consumer Units and small enclosures. (5704s, 5702s.)
Functions
CONTROL
Achieved by energising and de-energising the contactor coil, via an MK Time Switch or REC meter during
‘off peak’ hours as set by supply authorities. A coil status indicator is visible through the small window on
the front of the contactor.
Standards and approvals
All Sentry contactors in the range are designed
to fully comply with BS EN 61095
