Description

The Allen-Bradley 154-A22NB is a Bulletin 154 STC starting torque controller rated 22 A at 380-480V AC for 7.5-15 HP three-phase motors, with a factory setting of 30 percent initial torque for 4 seconds. Soft starters ramp up motor voltage gradually, reducing inrush current and mechanical stress during starting. The 154-A22NB is designed for the Allen-Bradley Bulletin 154 STC Line. It is typically used for reduced-torque motor starting.

Key ratings for the 154-A22NB: 22A, 380-480V AC, 50-60 Hz, 7.5-15 HP (11-15 kW). It connects through screw terminals, #14-#10 AWG / open style. Because it matches the original catalog number, it can be installed as a direct replacement in existing Bulletin 154 STC equipment, or added to expand a system. TCI currently stocks the 154-A22NB in Used condition. Select the condition above to see its price, or contact TCI for help confirming the right part for your application.
