The ABB AF116-30-11-14 is a three-pole electrical contactor rated at 104 A, part of ABB's AF contactor family. It's the component that switches power to motor loads, heaters, or other heavy inductive circuits in a control panel — the sort of part you'd find on a DIN rail inside a motor control center, handling the make-and-break duty cycle for a pump or conveyor drive.
104 A is the rated operational current in AC-3 duty (motor switching). That tells you this contactor can handle the inrush and break of a three-phase induction motor drawing up to that current under normal starting conditions. It's not a resistive-heater rating — if you're switching a purely resistive load, the same contactor will carry more current, but for motor loads this is the number that governs the sizing decision. The coil is listed as 250- (likely 250 VAC / VDC coil voltage, though the dash suggests a range or dual-frequency coil typical of ABB's AF series).
