AF2650-30-11
The ABB AF2650‑30‑11 is a heavy‑duty, 3‑pole power contactor from ABB’s AF large‑frame series, designed for high‑current, high‑power industrial switching. It is suitable for demanding applications such as large motor control, power distribution, generator switching, and heavy industrial loads, with main‑circuit ratings up to 1000 V AC. The contactor features an electronically controlled wide‑range coil (AC or DC), offering stable operation across a broad control-voltage range and built‑in surge protection, which improves reliability under fluctuating supply conditions. The block‑type modular design supports auxiliary contacts and accessories, making it flexible for various control or signalling circuit needs. In addition, its robust main contacts, bar‑type terminations, and high current capacity make it appropriate for industrial switchgear, motor control centers, and heavy‑duty power installations.
