Rated operational current spans 10 A at 24 V, stepping down to 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V — the contactor's thermal capacity derates with voltage, so size the load path against the specific control voltage in your circuit, not just the 10 A headline. Mounts via screw or snap-on to a DIN rail, occupying 45 mm of rail width — a single module slot in most enclosures. The IP20 front protection means it's suited for enclosed panel use where tools and fingers stay out of the live zone. RoHS compliance is indicated by a substance prohibition date of 07/01/2006, aligning with the EU RoHS directive's original effective date. No UL or CSA marks appear in the listing — verify jurisdictional acceptance if your panel requires them. ## Integration notes The screw terminals want a proper torque; spring-cage it is not, so keep a screwdriver with the right bit at the panel. Shock resistance is rated at 10 g for 5 ms and 5 g for 10 ms — adequate for most industrial panels but not for high-vibration mobile equipment without additional damping.","metaTitle":"Siemens 3RH1122-2AD00 SIRIUS Auxiliary Contactor, Size S00,","metaDescription":"Siemens SIRIUS auxiliary contactor 3RH1122-2AD00, size S00, 2 NO contacts, screw/snap-on mount, IP20 front.
