What this contactor is and what it handles
Its headline AC-3 rating is 11 A at 480 V, meaning it handles a 3-phase induction motor up to roughly 5.5 kW at that voltage — the figure that governs motor starting and running duty, not the higher AC-1 resistive rating. For DC switching, the contactor is rated 10 A at 24 V, 2 A at 48 V, and 0.6 A at 440 V — these matter when the same contactor controls DC brake coils or solenoid valves in the panel.
The S0 frame footprint is 45 mm wide × 85 mm tall × 97 mm deep — the 97 mm depth is the dimension to watch when clearing a shallow enclosure backplate or gland plate.
