What the 248 A AC-3 rating means for a motor load
The ABB AF265-30-11-14 is a 3-pole contactor rated 248 A in AC-3 duty, which is the standard category for switching squirrel-cage motors during starting and running. That 248 A figure governs the maximum motor full-load current it can switch — a 248 A AC-3 contactor typically handles a motor in the 130–160 kW range at 400 V, depending on the motor efficiency and starting current.
