Automatic Transfer Switch Controllers FT Series

FT70 Wye Delta (Star-Delta) Open

The FT70 Transfer Switch Controller uses a method of connecting the pump motor windings into wye configuration to start, then switching to a delta configuration to run which significantly reduces the starting current of the motor. Wye-Delta starting is the only method that has a starting torque efficiency of 100%. All Eaton FT Series controllers are supplied as Dual Utility controllers and meet FM 1321 / 1323 approvals.
