ABB CONTROL AF1650-30-11-70

The ABB CONTROL AF1650-30-11-70 is an ultra-high-performance 3-pole block contactor designed for extreme power and motor control applications. Rated up to 560 kW at 400 V AC (AC-3) and 900 hp at 480 V UL, it supports switching of power circuits up to 1650 A (AC-1). Equipped with AF wide-range coil technology (100–250 V AC/DC), the contactor ensures reliable operation under unstable supply conditions, reduces panel energy consumption, and integrates built-in surge protection for a compact, efficient solution. Pre-mounted auxiliary contacts and main circuit bars simplify installation, while the modular block design allows easy expansion with accessories.
