The stripped length is 10 mm. AWG equivalents are 2x (24... 14) for the auxiliary contacts — no special crimp tool needed beyond a standard ferrule press. ## Contact configuration and protection class Two normally-open (NO) auxiliary contacts, zero NC contacts — this is a dedicated make-contact block for signaling or interlock circuits in a SIRIUS compact feeder assembly. Front face carries IP20 finger-safe touch protection per IEC 60529, with vertical-contact rated touch protection — safe for live panel access during commissioning without additional shrouding. ## Environmental limits and storage Rated for operation from -20 °C to +60 °C with 10 % to 90 % relative humidity (non-condensing). Storage and transport range extends from -55 °C to +80 °C — wide enough for unheated warehouses or container shipping. ## Lifecycle and sourcing posture No stock-holding claim — each RFQ is handled individually.","metaTitle":"Siemens 3RA6911-2A SIRIUS Auxiliary Switch, 2 NO","metaDescription":"Siemens 3RA6911-2A SIRIUS auxiliary switch, 2 NO contacts, spring-loaded terminals.
