The ABB AX185-30-11-80 is a heavy-duty three-pole AC contactor designed for switching and controlling three-phase motors and power circuits in industrial electrical systems. It is part of ABB’s reliable AX185 contactor range and is identified by Product ID 1SFL491074R8011. This contactor is suitable for motor-control panels, industrial automation systems, pumps, fans, compressors, conveyors, HVAC equipment, processing machines, and other high-current electrical applications.

This model is fitted with an AC-operated control coil rated for 220–230V AC at 50Hz and 230–240V AC at 60Hz. The coil voltage is an important selection factor, so the AX185-30-11-80 should only be used where the available control-circuit supply matches these ratings. It should not be replaced with other AX185 versions that use 24V, 110V, 380V, or 400V control coils.

The contactor has three normally open main poles for switching three-phase loads. It also includes one normally open and one normally closed auxiliary contact, commonly known as 1NO + 1NC. These auxiliary contacts are useful for run feedback, interlocking, seal-in circuits, status indication, alarms, PLC signals, and control-relay functions. The built-in auxiliary contacts help simplify control-panel wiring and reduce the need for separate additional components.

The ABB AX185-30-11-80 delivers dependable performance in demanding 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 applications, it provides a rated operational current of up to 185A at common voltages including 220–240V, 380–400V, and 415V. At 400V AC-3 duty, it is suitable for controlling motors up to 90kW.
