The 10 % minimum relative humidity spec covers dry environments like switchgear rooms with active climate control. The 45 mm width and 57.5 mm height match the S00 footprint — two units sit side-by-side in a standard 600 mm enclosure bay with room for wiring ducts. Depth of 73 mm leaves clearance for front-access terminals and cable bends against the back panel. These are the minimum air gaps to adjacent metalwork or enclosure walls for proper arc quenching and heat dissipation. Terminal capacity accepts 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² solid or stranded conductors — covers daisy-chaining through auxiliary contacts without piggyback terminals. The three NO contacts are rated for AC switching at 50/60 Hz with a voltage range of 0.8 to 1.1 times rated voltage at 50 Hz and 0.85 to 1.1 at 60 Hz. Arcing time sits between 10 and 15 ms; the AC operating time is 4 to 15 ms. Maximum switching frequency is 10,000 operations per hour for DC loads. Thermal current ratings by voltage: 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, 0.26 A at 600 V, 1 A at 690 V. The 230 V rating is the same as the 24 V rating, which is unusual — the contacts are not derated at higher voltage until above 400 V. That figure governs the replacement interval in high-cycle applications like pick-and-place or packaging machinery. RoHS compliance date is 10/01/2009, meaning it meets the EU Restriction of Hazardous Substances directive since that date. The part is also REACH-compliant per Siemens standard declarations. UL and IEC certifications are standard for the SIRIUS family, though specific file numbers are not listed in this data set.","metaTitle":"Siemens 3RH2131-1AP00-1AA0 SIRIUS Auxiliary Contactor, 3 NO,","metaDescription":"Siemens SIRIUS 3RH2131-1AP00-1AA0 auxiliary contactor, 3 instantaneous NO contacts, Size S00. 10 A at 24 V.
