80 A switching, 250-50 VAC coil
The ABB AF80-30-11-14 is a three-pole contactor rated for 80 A continuous, with a 250-50 VAC coil. That 80 A figure is the continuous thermal current (Ith) at 40 °C ambient — the current the main poles can carry in free air without exceeding the temperature rise limit. For motor switching in AC-3 duty (starting and stopping squirrel-cage motors), the rated operational current drops; the 80 A frame typically handles a 37–40 kW motor at 400 V, but the exact AC-3 rating depends on the utilization category in your application. The coil range 250-50 VAC means the contactor picks up reliably anywhere from 250 V down to 50 V AC — useful when the control voltage sags under heavy load or when you're feeding it from a long cable run. No separate coil-voltage variant to stock; one part covers the band.
