The 24 V DC coil pulls 10 A at rated value — that 10 A figure is the make/break capability at 24 V DC, not the AC-3 motor rating, so when you see it on a BOM for a 24 V DC control circuit, this is the contactor that matches.
The S0 footprint — 61 mm wide, 85 mm high, 97 mm deep — is the standard size for this current range, so it drops into existing S0 cutouts or rail spacing without re-layout. Side clearance to adjacent devices is 6 mm; zero clearance needed upwards, forwards, backwards, or downwards, so you can pack it tight on the rail vertically.
Switching capability and thermal limits
The contactor carries auxiliary switch capability — useful for status feedback or interlocking without an add-on block. Mechanical life typical at 10,000,000 operations. The arcing time sits at 10 ms — fast enough for most PLC-driven cycles, but if your load has a long inductive tail, verify the switching frequency: at DC it's rated 1,500 1/h, at AC-1 maximum 1,000 1/h. Those are the thermal limits, not the mechanical ceiling.
