At 10 mm wide, it's the narrowest add-on in the S00 family; you can stack several across the face of a 45 mm contactor without blowing past the panel's DIN-rail envelope. Rated operational current hits 6 A at both 24 V and 230 V, and it carries a mirror contact per IEC 60947-4-1 — that's the feedback contact for safety circuits, so it mechanically tracks the main poles. ## Ratings that matter for the panel The AC-15 rating at 690 V is 1 A — that's the inductive load curve for contactor coils and solenoid valves, the typical use for an auxiliary on a motor starter. The 6 kV surge voltage resistance means it's good for 400 V line-to-line panels without extra suppression. The mirror contact feature (IEC 60947-4-1) is what lets you wire it into the safety chain without a separate feedback module. Snap-on mounting to the contactor — no tools, no DIN-rail clip. The 10 mm width means it fits between the contactor body and the next device on the rail; depth is 66 mm, height 57.4 mm. Wire range accepts 2x (0.5 to 1.5 mm²) solid or 2x (0.75 to 2.5 mm²) stranded, or AWG 20-16 / 18-14.","metaTitle":"Siemens 3RH6911-1DA11 SIRIUS Auxiliary Switch, Snap-On S00,","metaDescription":"Siemens SIRIUS 3RH6911-1DA11 auxiliary switch, 10 mm wide, snap-on S00 contactor relay.
