The 2 NO configuration (no NC, no delayed or leading/lagging contacts) makes it a straightforward pick for adding a single set of auxiliary contacts to a contactor or for standalone interposing relay duty. The 45 mm width and 57.5 mm height fit the S00 footprint shared across the SIRIUS contactor family, so it aligns mechanically with a 3RT2 contactor of the same frame. ## Electrical ratings and contact reliability Rated surge voltage resistance is 6 kV, which aligns with basic insulation coordination for 400 VAC control circuits in pollution degree 3 environments. The auxiliary switch block is field-extendable (Product Extension Auxiliary Switch = Yes), so additional contact blocks can be ganged on if the 2 NO count needs to grow later.","metaTitle":"Siemens 3RH1122-1AF00-ZX95 SIRIUS Auxiliary Contactor, S00,","metaDescription":"Siemens SIRIUS 3RH1122-1AF00-ZX95 auxiliary contactor, size S00, 2 NO contacts, rated 10 A at 24 V.
