ABB CONTROL AF1350-30-11-70
The ABB CONTROL AF1350-30-11-70 is a heavy-duty 3-pole block contactor engineered for high-power motor control and power switching applications. Rated up to 475 kW at 400 V AC (AC-3) and 800 hp at 480 V UL, it supports power circuits up to 1350 A (AC-1). ABB’s AF wide-range coil technology (100–250 V AC/DC) ensures reliable operation across unstable networks while reducing panel energy consumption. Built-in surge protection, pre-mounted auxiliary contacts, and main circuit bars deliver a compact, installation-ready solution with excellent scalability through ABB’s modular accessory system.
