The Allen-Bradley 21T-380097-A01 LiquiFlo transformer kit, rated at 3 kVA and 120 Volts AC, is designed to address and prevent issues such as damage-inducing currents and line voltage transients affecting LiquiFlo 2.0 AC drives, while also minimizing line noise feedback to the power supply. Essential for proper functioning, installation requires a power disconnecting device, and if using a circuit breaker, its trip rating must accommodate the transformers inrush current. Specifically for Frame 4 drives, this transformer kit provides a critical role in maintaining drive integrity and can rectify issues such as "AC Line Lost Fault" and "Rctfr Not OK Fault" by inspecting and replacing critical fuses.
