For inductive loads at AC-15, it delivers 1 A at 690 V. The mirror contact feature per IEC 60947-4-1 ensures that the N/C contact cannot close if the N/O is welded — critical for safety circuits in motor starters. The block is IP20 on the front, suitable for enclosed panel use. The block snaps onto the front of any SIRIUS S00 contactor (e.g., 3RT201 or 3RT202 series). Dimensions are 36 mm wide, 37.5 mm high, and 43.7 mm deep — it adds minimal depth to the contactor assembly. Terminals accept 2 x (0.5 to 1.5 mm²) solid or 2 x (0.75 to 2.5 mm²) stranded wire, with equivalent AWG 20-16 and 18-14. Fine-stranded wire with ferrules is also accommodated. The substance prohibition date of 05/01/2012 indicates RoHS compliance from that date forward.","metaTitle":"Siemens 3RH6911-1HA11 SIRIUS Auxiliary Switch, 1 N/O + 1 N/C","metaDescription":"Siemens 3RH6911-1HA11 SIRIUS auxiliary switch block, snap-on for S00 contactors. 1 N/O + 1 N/C, rated 10 A at 24 V, IP20 front.
