The 1321-3TH275-BB transformer is an Allen-Bradley manufactured 3-phase isolation transformer. The isolation transformer is designed to meet standard power ratings, standard voltage ratings, and the harmonics of Allen-Bradley 1336 variable frequency speed drives. It is a power transformer component with a floor-mounted architecture. It comes with a power rating of 275 kVA. It supports both primary and secondary voltage ratings of 460 Volts AC. The isolation transformer is mainly used to transfer power from an alternating current source to some equipment while isolating the powered device from the power source. The 1321-3TH275-BB transformer is generally used for industrial safety and device protection purposes. The isolation transformer comes with a K-factor of 4. It is equipped with thermostats with 1 normally closed contact in every coil. These coils are wired in series and are they are integral features on all units.
The 1321-3TH275-BB transformer works in a duty cycle. Every single duty cycle starts every 2 hours. The transformer is equipped with primary delta and secondary wye windings. Both windings have a frequency of 60 Hertz for normal operating conditions. All the 1321 series isolation transformers are protected with Class 220 insulation system which ensures that the variable frequency drive is properly insulated. The 1321-3TH275-BB transformer can be operated at up to an altitude of 1000 meters above the sea level without any performance reduction. The 1321-3TH275-BB isolation transformer comes with a power rating of 250 Horsepower. The isolation transformer comes with a NJ1 construction and it has a well-equipped and ventilated construction design.
