What this part is and what it does
The ABB AF140-30-22-11 is a 3-pole contactor rated at 130 A, with a coil voltage range of 20-6 V. It is part of ABB's AF contactor family, designed for switching motor loads and resistive loads in industrial control panels. The 130 A rating in AC-3 duty means it handles motor starting currents up to that level without welding the main contacts — the rating that governs real-world fit for pump, fan, and conveyor drives.
Panel integration and deployment context
Mounts on DIN rail in a standard control-panel enclosure. The 130 A frame size requires adequate side clearance for heat dissipation and wiring access.
