Phase Sequence Relay Connection

If the control relay coil or contacts the phase failure relay contacts or the shunt trip coil does not have the same voltage rating as the motor control transformers may be interposed where needed.

Phase sequence relay connection.

Through the cr contacts and phase failure relay contacts. The k8ak ph1 output contacts are normally operative. Phase loss detection while the motor is operating. Wiring example timing charts phase sequence and phase loss operation diagram note.

In this video we explain phase failure relay and also explain phase failure relay connection in star delta starter we use phase failure relay for protection.
