That 248 A figure is the conventional free-air thermal current (Ith) — the current the main poles can carry continuously in open air. For motor switching duty (AC-3), the actual make/break rating will be lower; check the AC-3 column on the nameplate before sizing for a specific motor load. The coil accepts both AC and DC without needing a separate rectifier or economizer circuit, which simplifies panel wiring and reduces the parts count on the DIN rail. The contactor carries 2 normally-open and 2 normally-closed auxiliary contacts (the '22' in the order code). These are rated for control-circuit switching and share the same coil supply — verify the free-wheel diode polarity on the coil if the control system uses DC switching, per standard practice for inductive loads.
For a BOM-line commitment, the 248 A rating and the wide coil voltage range (100-250 VAC/DC) are the two specs that confirm fit for most 3-phase motor or resistive load panels.
