ABB A145-30-11-84 is a three-pole, three-phase magnetic contactor from ABB’s A‑line family, driven by a 110–120 V AC coil to switch three normally open main contacts (3NO) and an auxiliary contact (1NO/1NC) for signaling or interlock circuits. The main contacts are rated up to 230 A and the device is suitable for switching up to 600 V AC, with horsepower equivalents of 50 HP at 240 V, 100 HP at 480 V, and 125 HP at 600 V. This configuration is designed for reliable control of medium-sized three‑phase motors in industrial panels, providing robust motor-starting and load-switching performance in demanding environments.
