Its AC-3e rating of 24 A at 690 V means it handles three-phase induction motors up to that current in the most common switching duty — starting and stopping a running motor. At 400 V and 60 °C ambient, it delivers 38 kW, which is the number most panel builders size against for a 400 V line. Screw-type terminals on both the main and auxiliary/control circuits accept up to 16 mm² (2x) solid or stranded wire, or 2x 18–2 AWG. The 55 mm width and 115 mm depth mean it fits standard 200 mm deep enclosures with room for side-by-side mounting.
Where it goes and what it needs
Rated insulation voltage is 690 V, so it's suited for 400 V and 690 V line-to-line systems. The operating temperature range of -25 to +60 °C covers most indoor panel environments; storage range of -55 to +80 °C handles warehouse extremes. Mounting position allows +/-180° rotation on a vertical surface and tilting forward/backward by +/-22.5°, giving flexibility in tight enclosures.
The part carries the SIRIUS brand, which is Siemens' standard industrial contactor family with broad UL/CSA/CE acceptance across markets.
