The ABB A145‑30‑11 is a 3‑phase, 3‑pole AC magnetic contactor from ABB’s “A‑line / A‑series.” It is designed to switch and control three‑phase motors or general power circuits in industrial, commercial, or HVAC environments. The contactor uses a standard AC coil, and includes both main power contacts and auxiliary contacts for control or signalling. Its robust design, wide operating voltage range, and ability to handle high currents make it suitable for motor starting/stopping, bypass/isolation, distribution circuits, and other heavy‑duty switching applications.
