The coil draws 0.8–1.1 A at 50 Hz and 0.85–1.1 A at 60 Hz. Three NO contacts give you three independent signal paths — common for interlocking, status feedback, or extending a PLC output. The 5 million mechanical cycles typical life means it'll outlast most machine rebuilds in a dry panel. Contact reliability is rated at one incorrect operation per 100 million cycles at 17 V, 1 mA — so it's trustworthy for dry-circuit logic signals, not just power switching. Screw terminals accept 2x 0.5–1.5 mm², 2x 0.75–2.5 mm², or 2x 4 mm² — solid or stranded. That's enough for control wiring up to 4 mm² on the same terminal. Size S00 footprint: 90 mm wide, 57.5 mm tall, 72 mm deep. Screw it down or snap it onto a DIN rail — both methods are listed. Shock-rated at 10g / 5 ms and 5g / 10 ms — fine for most industrial panels, but worth noting for high-vibration applications like near a large motor or on mobile equipment. An auxiliary switch block can be added to the front (product extension auxiliary switch is supported), so you're not stuck with the three NO contacts if the job grows. RoHS compliance date is 2006-07-01 (substance prohibition), so it meets the EU RoHS directive.","metaTitle":"Siemens 3RH1431-1AP00 SIRIUS Auxiliary Contactor, 3 NO + 0 N","metaDescription":"Siemens 3RH1431-1AP00 SIRIUS auxiliary contactor, size S00, 3 NO instantaneous contacts, screw/snap-on mounting, 24 VDC coil, rated 10 A at 24 V.
