The Allen-Bradley 154-A11NB Starting Torque Controller is tailored for optimizing the start-up profile of both single-phase and three-phase industrial AC motors, effectively reducing mechanical stresses associated with sudden torque increases. Engineered for a voltage range of 380-480 VAC at 50/60 Hz, this open-type controller supports smoother motor initiations with selectable torque values from 10% to 80% of the locked rotor torque and adjustable start times between 0.1 and 4.5 seconds. Featuring a current rating of 11 Amperes and a power capacity of 4 kW or 7.5 HP, it includes an RC Snubber network for transient protection and is certified by CE, CSA, and UL, making it suitable for various applications such as conveyors, material handling equipment, and elevators.
