BRAH A145-30 Contactor

Allen‑Bradley/ABB A145‑30 Contactor is a three‑pole, AC‑operated motor‑contactor in the A‑Line family, built to switch 3‑phase loads at up to 600 V AC with a main current rating around 130 A. It provides HP ratings of roughly 50 HP at 240 V, 100 HP at 480 V, and 125 HP at 600 V, making it suitable for controlling medium‑size motors and fans in industrial equipment. The A145‑30 family is available in multiple coil voltages to suit regional power supplies, including 110–120 V AC options (examples such as A145‑30‑11‑84) and 220–230 V AC options (examples such as A145‑30‑22‑80), with coil configurations routinely paired to the main contacts for reliable switching. Auxiliary contact arrangements vary by variant, spanning from 1 NO/1 NC to 2 NO/2 NC, enabling control circuits or signaling contacts alongside the main contacts. Common applications include primary motor control for pumps, conveyors, and processing equipment where robust, code‑compliant 3‑phase switching is required and replacement parts align with the A‑Line/ABB family.
