The ABB A16-40-00-80 is a 4-pole non-reversing contactor from the A16 series, with a coil rated for 220 V at 50 Hz and 240 V at 60 Hz.
The non-reversing type means this contactor has a single set of power poles and a single coil — it closes in one direction only. It is not mechanically interlocked for forward/reverse duty. If your circuit requires motor reversing, you would need two of these with an external mechanical interlock, or a dedicated reversing contactor. The 240 V 60 Hz coil is a standard control voltage in North American panels; the 220 V 50 Hz rating covers European-line applications. Verify the coil pick-up and drop-out voltage against your control transformer output — the coil holds at nominal and drops out reliably below about 180 V AC.
