The ABB AX185-30-11-84 is a robust three-pole AC contactor designed for reliable switching and control of three-phase motors and power circuits in industrial electrical panels. This ABB contactor is identified by Product ID 1SFL491074R8411 and belongs to the trusted AX185 contactor range. It is suitable for machine builders, panel manufacturers, maintenance professionals, HVAC systems, pumps, compressors, conveyors, fans, and other heavy-duty industrial applications.

This model is fitted with an AC-operated control coil rated for 110V at 50Hz and 110–120V at 60Hz. The coil voltage is an important selection factor, so this AX185-30-11-84 version should only be used where the control circuit matches the required 110V AC supply. It should not be substituted with visually similar AX185 models that use 24V, 220V, 230V, or 400V control coils.

The contactor features three normally open main contacts for switching three-phase loads. It also includes one normally open and one normally closed auxiliary contact, commonly written as 1NO + 1NC. These auxiliary contacts can be used for operating feedback, electrical interlocking, seal-in circuits, indicator lamps, alarms, PLC signals, and control relay wiring. This built-in auxiliary arrangement helps simplify many conventional motor-control and automation panel circuits.

The ABB AX185-30-11-84 offers strong performance for high-current industrial applications. It has a conventional free-air thermal current rating of 250A at 40°C in AC-1 duty. For AC-3 motor-control duty at 55°C, it is rated at 185A for 220–240V, 380–400V, and 415V applications. At 400V AC-3 duty, it can control motors up to 90kW, making it suitable for demanding three-phase motor installations.

The AX185 contactor range is designed for controlling motors and power circuits with a main circuit operational voltage of up to 1000V AC. The contactor is built according to relevant IEC and EN standards for low-voltage switchgear and motor-control equipment. Its block-type construction supports compatible ABB accessories and add-on auxiliary contact blocks, helping panel builders customise the control arrangement when additional functions are required.
