Its headline rating is 9 A in AC-3 utilisation category at up to 440 V, which means it switches standard three-phase induction motors up to that current — a common size for small conveyors, pumps, and fans in light industrial panels. The 24 V AC coil (50/60 Hz) keeps the control circuit low-voltage for operator safety.
Compliant with EN/IEC 60947-1, -4-1, and -5-1, plus the Chinese GB/T equivalents — so it passes for both European and China-market machine builds. Fire resistance tested at 850 °C per IEC 60695-2-1, and protective treatment TH (pollution degree 3) per IEC 60068-2-30 handles humid, non-condensing environments.
