It is rated 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V — those are the AC-15 / DC-13 style switching capacities you'd expect for control-circuit isolation, not power switching. The contact reliability spec — one incorrect switching operation in 100 million at 17 V, 1 mA — tells you this part is built for dry-circuit signal integrity, not just power contacts. That matters when you're switching PLC inputs or relay coils where the load current is low and oxide films don't self-clear. ## Mounting and integration — DIN rail or screw, with position flexibility That gives panel builders room to orient the contactor for wire routing without worrying about derating the switching capacity. Dimensions are 45 mm wide, 60 mm high, 73 mm deep — the S00 footprint fits alongside SIRIUS contactors and overload relays in a compact control panel. ## Wiring and conductor compatibility Solid conductors from 0.25 mm² to 2.5 mm² are accepted. That range covers most control-circuit wiring. Substance prohibition date is 07/01/2006, aligning with RoHS compliance. Shock resistance is rated at 10 g / 5 ms and 5 g / 10 ms.","metaTitle":"Siemens 3RH1122-2AF00-0TK0-ZX95 SIRIUS Auxiliary Contactor,","metaDescription":"Siemens SIRIUS 3RH1122-2AF00-0TK0-ZX95 auxiliary contactor, size S00, 2 instantaneous NO contacts, 10 A at 24 V, IP20 front, screw/snap-on mount, 73 mm depth.
