The coil pulls 37 VA on pick-up and holds at 5.7 VA, so the control transformer needs to be sized for that inrush, not just the sealed draw. Mechanical life is listed at 30 million operations typical, so this relay will outlast most panels it goes into. Width is 45 mm, depth 73 mm, height 57.5 mm — that is a standard S00 footprint, so it shares the same slot as any other SIRIUS S00 auxiliary contact block or contactor. That helps when you are squeezing it into a crowded backplane or an angled sub-panel. Terminals accept 2 x (0.5 to 1.5 mm²), 2 x (0.75 to 2.5 mm²), or 2 x 4 mm² solid or stranded. Finely stranded wire with ferrule is also supported. ## Contact ratings and switching capacity The auxiliary contacts are rated for AC-12 at 6 A (resistive) and DC-12 / DC-13 at 1 000 operations per hour. Specific voltage-based current ratings: 6 A at 24 V, 3 A at 110 V, 1.2 A at 220 V, 10 A at 230 V, 3 A at 400 V, and 1 A at 690 V. That 10 A at 230 V is the highest figure — it applies at that voltage, not across the board. For DC switching, the 24 V 6 A rating is the one to design around; the curve drops fast as voltage rises. RoHS compliance date is listed as May 1, 2012, which covers the EU RoHS 2 (2011/65/EU) directive. The part also carries the standard SIRIUS approvals — UL, CSA, CE — though the specific certification numbers are not in this record. For a compliance audit, the manufacturer's declaration is available on request.","metaTitle":"Siemens 3RH6131-1AH00 SIRIUS Contactor Relay, 1NC+3NO, AC Co","metaDescription":"Siemens 3RH6131-1AH00 SIRIUS contactor relay, size S00, 1 NC + 3 NO auxiliary contacts, AC coil. 45 mm wide, screw and snap-on 35 mm rail mount.
