Product details

The S00 footprint — 45 mm wide, 70 mm high, 73 mm deep — keeps it compact for dense DIN-rail layouts.

The contact ratings span the control-voltage range you'd expect in a 24 V to 690 V panel: 10 A at 24 V and 230 V, 3 A at 110 V and 400 V, down to 0.26 A at 600 V. Arcing time runs 10–15 ms; at DC the rated switching frequency is 10 000 operations per hour. These numbers tell you the contactor handles typical PLC and relay pilot-duty loads, not motor inrush — it's an auxiliary, not a power contactor.
