It switches 12 A in AC-3 duty (motor starting) at up to 440 V, and carries a 380 V AC coil at 50/60 Hz. The contactor includes one normally-open auxiliary contact. The contactor is rated for operation up to 3000 m altitude without derating.
For resistive loads (AC-1), the contactor can carry a higher current, but for motor duty, the AC-3 figure governs. The 380 V AC coil is line-powered, so no separate control transformer is needed if the panel supply matches. The contactor complies with EN/IEC 60947-4-1 (the main standard for contactors and motor-starters), EN/IEC 60947-5-1 (control circuit devices), and GB/T equivalents. Fire resistance tested to 850 °C per IEC 60695-2-1. The TH protective treatment (pollution degree 3) means it withstands humid, mildly corrosive environments typical of industrial control panels.
