It's the part you reach for when a motor contactor or a PLC output needs more signal-side switching capacity — a clean way to mirror a coil state or interlock a sequence without adding a second contactor. Rated operational current is 10 A at both 24 V and 230 V, which covers most control-circuit loads in a 400 V panel.
The S00 footprint — 45 mm wide, 70 mm tall, 121 mm deep — is the smallest Siemens contactor frame, so it tucks into tight enclosure rows without crowding adjacent devices. Clearance spacing: 10 mm upwards, downwards, and forwards; 6 mm at the side.
Contact ratings and switching performance
Four NO contacts rated for continuous current at 24 V (10 A), 60 V (4.7 A), 110 V (3 A), 220 V (1.2 A), 230 V (10 A), 400 V (3 A), 440 V (0.5 A), 500 V (2 A), 600 V (0.26 A), and 690 V (1 A). Arcing time runs 10 to 15 ms; AC switching time is 4 to 15 ms. The DC switching rate hits 10 000 operations per hour.
