Size S00 footprint is 45 mm wide × 57.5 mm high × 72 mm deep. Solid-wire termination accepts 2× (0.5–1.5 mm²), 2× (0.75–2.5 mm²), or 2× 4 mm² per terminal — covers most control-circuit wiring from signal-level to moderate power. ## Contact ratings and switching reliability Rated 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V — these cover the common control voltages across global panels. Shock resistance is 10g / 5 ms and 5g / 10 ms, which suits installation on vibrating machinery or near motor starters without contact chatter. Pollution degree 3 — suitable for industrial atmospheres with conductive pollution. RoHS compliance date is 2006-07-01, covering the EU directive.","metaTitle":"Siemens 3RH1122-1AD00 SIRIUS Auxiliary Contactor, S00, 2 NO","metaDescription":"Siemens SIRIUS 3RH1122-1AD00 auxiliary contactor, size S00, 2 NO + 2 NC contacts, 24V coil 10A rated, screw/snap-on mount, IP20 front.
