The ABB AX185-30-11-81 is a robust and high-performance 3-pole AC contactor designed for reliable switching and control of three-phase motors and power circuits in industrial applications. Manufactured by ABB, this contactor is suitable for control panels, motor starter assemblies, automation systems, pumps, fans, compressors, conveyors, HVAC equipment, and other heavy-duty electrical installations.

This model is supplied with a 24V AC control coil compatible with both 50 Hz and 60 Hz power supplies. It is important to select the correct coil-voltage version during installation; the AX185-30-11-81 is specifically designed for 24V AC control circuits. The contactor features three normally open main poles, making it suitable for switching three-phase loads safely and efficiently.

The ABB AX185-30-11-81 includes one normally open and one normally closed auxiliary contact (1NO + 1NC). These auxiliary contacts can be used for electrical interlocking, feedback signals, status indication, seal-in circuits, alarms, PLC integration, and control relay applications. This helps reduce the need for additional control components in many industrial panel designs.

With an AC-1 current rating of 250A at 40°C, this contactor is built for demanding power-switching duties. For AC-3 motor-control applications, it offers a rated operational current of up to 185A at common operating voltages such as 380V, 400V, and 415V. At 400V AC-3 duty, it is suitable for motor loads up to 90 kW. These ratings make it an excellent choice for high-capacity motor control and industrial power applications.
