Its AC-3 rating is 80 A at ≤440 V — the current it can switch a three-phase induction motor under full load.
Where it fits in a panel
The 85 mm width and 127 mm height keep it compact for a 3-pole contactor at this rating.
Environmental tolerance and compliance
The TH protective treatment (pollution degree 3 per IEC 60068-2-30) means it withstands humid, mildly corrosive atmospheres — typical in HVAC or pump rooms, but not for direct washdown zones. Standards compliance covers EN/IEC 60947-4-1 (the main contactor standard), plus GB/T equivalents for Chinese markets.
