RAT2002 / RAT3008 / RAT3044 – Time-lag Auxiliary Relays
Products family : Time-lag Relay
Sector : Auxiliary relay
The RAT auxiliary relays are the CEE family of time-lag relays designed for signalling and control.
They are used in sequential control schemes requiring either a time-delay on pick-up (energisation: the output contacts change position at the end of the preset time initiated by the closure of a control contact external to the relay), or a time-delay on drop-off (de-energisation: the same operation occurs at the end of the preset time initiated by the opening of a control contact external to the relay).
The rating and clearances used for the output contacts allow direct control of switching equipment.
These relays can be fitted with:
– 2 change-over time delayed contacts (RAT 2002)
– 8 change-over time delayed contacts (RAT 3008)
– 4 change-over time delayed and 4 instantaneous contacts (RAT 3044).
