The 1321-3TH014-BA transformer is an industrial power component that is manufactured by Allen-Bradley. It is a 3-phase drive isolation transformer. It comes with a voltage rating of 460 Volts AC. The transformer is designed to be mounted in an industrial location such as a factory. It has a 14 kVA rating. The secondary voltage of the transformer is rated at 230 Volts AC. The transformer has a delta primary winding and a wye secondary winding with a frequency of 60 Hertz. It is manufactured by using wound aluminum. A neutral terminal is available in the transformer for operator use. It can tap standard voltage easily. The 1321-3TH014-BA transformer has a class 220 insulation system and it can support up to 150 degrees Celsius ride temperature in an ambient temperature of 40 degrees Celsius. The transformer can work with a peak temperature of 40 degrees Celsius with a 24-hour average temperature of 30 degrees Celsius.

The 1321-3TH014-BA transformer is rated to be 98% efficient. It can be operated at up to an altitude of 1000 meters above the sea level without getting derated. It has been listed with the UL standards. It meets all the specifications for the EMC standards. It is equipped with a common mode choke device which is compatible with all of the 1336 adjustable frequency AC drives. The common mode choke device is used to guard the 1321-3TH014-BA transformer against interference with other electrical equipment. It also reduces the PWM carrier frequency and decreases the common mode noise interference.
