It snaps onto the front of the contactor without tools, adding one N/O and one N/C auxiliary contact to the base unit. Rated for 10 A in AC-12 duty and 6 A at 24 V in AC-15/DC-13, it handles typical PLC output and relay coil switching in control panels. The 10 million operating cycles mechanical life means it outlasts most contactors it rides on. That 600 V rating matters if you're switching DC bus voltage in a drive cabinet. Size S00 means the switch block is 23.6 mm wide, 27.5 mm tall, and 38.6 mm deep — it adds about 40 mm to the depth of the contactor it mounts on. Snap-on mounting means no screws; it clips onto the front of the contactor relay or power contactor. Finely stranded with ferrule is also supported. Front IP20 means the live parts are touch-safe once mounted inside a panel; the switch itself isn't rated for washdown environments. The mirror contact feature per IEC 60947-4-1 means the N/C contact mechanically mirrors the N/O contact position — critical for safety circuits where you need positive indication that the main contacts are open. RoHS compliance date is May 1, 2012. No minimum order quantity beyond what the distributor sets; sourced through authorized Siemens distribution channels.","metaTitle":"Siemens 3RH6911-1AA10 SIRIUS Auxiliary Switch, 6 A at 24 V","metaDescription":"Siemens 3RH6911-1AA10 SIRIUS auxiliary switch block, size S00, snap-on mounting.
