It is rated for 10 A at 24 V, with a surge voltage resistance of 6 kV and pollution degree 3 per IEC 60947-1. ## Contact ratings and switching reliability The 3RH1131-2AN20 is rated for 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V. For DC switching, it handles 1 A at 110 V and 0.27 A at 220 V. The mechanical life of the contactor is 30 million operations typical. The contactor accepts solid conductors of 2x (0.25 to 2.5 mm²) per terminal. The depth is 73 mm, width 45 mm, height 60 mm — this fits the standard S00 footprint on a DIN rail. Shock resistance is 10g at 5 ms and 5g at 10 ms. ## Compliance documentation The part carries a substance prohibition date of July 1, 2006, indicating RoHS compliance per the EU directive. No UL or CSA listing is explicitly stated in the evidence, but the IEC ratings are standard for European panel builds.","metaTitle":"Siemens 3RH1131-2AN20 SIRIUS Auxiliary Contactor, Size S00,","metaDescription":"Siemens 3RH1131-2AN20 SIRIUS auxiliary contactor, size S00. 3 NO + 1 NC contacts, rated 10 A at 24 V.
