It carries a 25 A rating in AC-3 and AC-3e duty at ≤440 V, meaning it is sized for switching three-phase induction motors up to that current — the AC-3 category per EN/IEC 60947-4-1 covers starting and disconnecting squirrel-cage motors under load. The 380 V AC coil at 50/60 Hz pulls in the main contacts, and the integrated 1 NC auxiliary contact provides a feedback or interlock signal without a separate block.
For resistive loads (AC-1), the same contactor can handle higher continuous current, but the AC-3 figure is the one that decides fit for a motor starter. Ambient operating temperature range is -5 to 55 °C, with storage from -60 to 80 °C, and it operates at altitudes up to 3000 m without derating.
It also meets GB/T 14048.1.4, and.5 (Chinese national standards), and portions of EN/IEC 60335 (household appliance safety) for glow-wire and fire resistance.
