Part overview and deployment context
The Siemens SIRIUS auxiliary contactor 3RH2131-1AV60 is a size S00 unit rated 10 A at 24 V. It mounts via screw or snap-on onto 35 mm DIN rail, making it a direct fit for standard control panels. The 45 mm width and 73 mm depth mean it occupies one standard module slot, leaving room for adjacent devices in a dense layout.
Electrical ratings and what they mean for fit
The 10 A rating at 24 V is the continuous current the contacts can carry in a DC control circuit at that voltage. At 230 V it also carries 10 A, but at 400 V it drops to 3 A and at 600 V to 0.26 A. That derating curve matters when the contactor is switching a mixed-load panel: if your BOM calls for switching a 400 V pilot circuit at 3 A, this unit covers it; for a 600 V circuit at even 0.5 A, it does not.
Mounting and panel integration
Fastening method is screw and snap-on onto 35 mm standard mounting rail. The mounting position permits +/-180° rotation on a vertical surface and tilt forward/backward by +/-22.5°. Clearance requirements: 10 mm upwards, forwards, and downwards; 6 mm at the side. That 6 mm side clearance is tighter than some competing blocks — plan your DIN rail spacing accordingly.
Environmental and compliance
Operating temperature range -25 to +60 °C; storage range -55 to +80 °C. Pollution degree 3 — suitable for industrial environments with conductive pollution or dry non-conductive pollution that becomes conductive. Substance prohibitance date 10/01/2009 aligns with RoHS/REACH compliance deadlines.
