It carries three power poles, each with 3 NO contacts, rated for 18 A in AC-3 duty — the utilisation category for squirrel-cage motor switching. The 400 V AC coil is built into the assembly, so this is a drop-in unit for a star-delta transition scheme, not a bare contactor you wire yourself.
Operating altitude goes to 3000 m without derating, so it's fine for most plant floors and high-altitude installations up to that level.
Environmental and mechanical toughness
Climatic withstand conforms to IACS and IEC 60947-1 Annex Q Category D, with protective treatment TH per IEC 60068-2-30 for tropical humidity. Vibration tolerance: 2 Gn contacts open, 4 Gn closed; shock tolerance 10 Gn open, 15 Gn closed — solid for conveyor and pump applications with moderate vibration.
