The 220 V AC 50 Hz coil is standard for European control circuits.
The AC-1 and AC-3 utilisation categories cover both resistive loads (heating, lighting) and motor starting/running. The single NO main pole and the auxiliary contact block (2 NO + 2 NC) give you one switched power path plus four auxiliary signals for feedback or interlocking. The 220 V AC coil is specific to 50 Hz mains; verify your control voltage matches before panel integration.
