It is rated AC-3 at 16 A up to 440 V, with a 220...230 V AC coil, and carries one normally-open auxiliary contact.
Key ratings and their meaning
AC-3 at 16 A is the motor-switching rating — the contactor is designed for starting and stopping squirrel-cage induction motors under load, not just resistive heating elements. At ≤440 V this is the duty that governs real motor sizing. The 220...230 V AC coil is a standard control voltage for industrial panels in regions using 230/400 V distribution. Coil dropout and pickup thresholds follow IEC 60947-4-1; expect pickup at roughly 85% of rated voltage and dropout below 70%. Mechanical robustness is specified to 10 Gn shocks on Y and Z axes with the contactor closed, and 4 Gn vibration across 5...300 Hz — this suits installation on machinery subjected to moderate vibration, such as conveyor drives or pump skids.
Integration notes
The IP20 housing means no additional finger-duct shielding is required inside the panel, but the contactor must be mounted in a clean, dry enclosure. The preassembled reversing busbar means the main power connections are fixed; wire the line-side supply to the common input and the motor to the two output terminals. Verify the busbar torque marking before commissioning. Operating altitude is rated to 2000 m without derating. Above that, expect a reduction in dielectric withstand and thermal dissipation — consult the thermal derating curve if installed above 2000 m.
