The ABB A16-40L-00-81 is an A16-series contactor carrying a 30 A / 600 V tungsten-filament load rating — the kind of inrush a standard resistive or motor rating won't handle cleanly. That tungsten spec matters when you're switching incandescent or high-intensity discharge lighting banks; the cold-filament surge can weld standard contacts on the first cycle.
The 30 A / 600 V figure is not a general-purpose motor rating. It is a tungsten (incandescent lamp) load rating — the contactor is designed to handle the cold-filament inrush that can be 10–15 times the steady-state current. For motor or resistive heating duty, you would need to check the AC-1 or AC-3 ratings separately; those are not listed here, so the tungsten rating is the only confirmed switching capability on record.
The 30 A tungsten rating suggests a panel footprint sized for lighting contactor duty — expect a 45 mm wide housing, typical for this class. Verify the coil voltage and auxiliary contact configuration against your control circuit before wiring; the order code suffix carries that detail, but the evidence here does not break it out.
