SIRIUS auxiliary contactor, size S00 — 3NO+1NC, screw terminals
The 3RH2131-2AP00-ZW97 is a Siemens SIRIUS auxiliary contactor in frame size S00, delivering 3 normally-open and 1 normally-closed instantaneous contacts. Rated operational current varies by voltage and duty: 10 A at 24 V and 230 V, 4.7 A at 60 V, 3 A at 110 V and 400 V, 1.2 A at 220 V, 0.5 A at 440 V, 2 A at 500 V, 0.26 A at 600 V, and 1 A at 690 V. These are the contact ratings — match your control voltage to the appropriate column for thermal capacity.
Snap-on mounting onto 35 mm standard mounting rail; screw terminals accept 2x (0.5 to 4 mm²) solid or stranded wire. The S00 frame size keeps the footprint compact — 45 mm wide, 70 mm high, 73 mm deep — so it fits tight DIN-rail layouts alongside contactors and overload relays. Pollution degree 3 rated, so it handles conductive dust environments common in industrial panels. Relative humidity minimum 10 %. The part is RoHS-compliant per the 10/01/2009 substance prohibition date.
