At 25 mm wide, it occupies one standard 18 mm DIN-rail spacing unit, so it fits into the same panel layout as the SIRIUS 3RA6 and 3RA7 series devices without crowding adjacent components. ## Environmental limits and panel safety Rated for operation from -20 to +60 °C with 10 to 90 % relative humidity, this cable handles the thermal range inside a ventilated industrial enclosure without derating. Storage and transport limits extend from -55 to +80 °C, so it tolerates warehouse and trucking extremes before installation. The front face carries IP20 finger-safe touch protection per IEC 60529, meaning the exposed connector surface meets the standard probe test — no live parts are accessible during maintenance with the panel door open.","metaTitle":"Siemens 3RA6931-0A SIRIUS connecting cable, 14-pole","metaDescription":"Siemens 3RA6931-0A SIRIUS connecting cable, 14 poles, 25mm width, IP20 finger-safe front.
