The three slots accept up to three compact feeder modules, letting you build a multi-motor group from a single mounting point. The 135 mm width and 197 mm height mean it occupies three standard 45 mm-wide DIN spaces, so factor that into your enclosure fill. ## Environmental and protection specs Rated IP20 on the front — finger-safe touch protection per IEC 60529, suitable for enclosed panels where no water spray is present. Vibration resistance covers 4 to 5.8 Hz at 15 mm amplitude and 5.8 to 500 Hz at 2 m/s² over 10 cycles; shock rated at 6 m/s² semi-sinusoidal, 10 ms, three axes both directions.","metaTitle":"Siemens 3RA6823-0AC SIRIUS Triple Extension Block, 63A","metaDescription":"Siemens 3RA6823-0AC SIRIUS triple extension block, 63A at 400V AC-3, 3 slots for compact load feeders, spring terminals, IP20.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Starters"],"specifications":{"Depth":"100mm","Width":"135mm","title":"3RA6823-0AC","Height":"197mm","description":"Triple extension block Connection main circuit: Spring-type terminal 3 slots for compact load feeders","During Storage":"-55 ... +80°C","lifecycle_stage":"current","During Operation":"-20 ... +60°C","During Transport":"-55 ... +80°C","Fastening Method":"screw and snap-on mounting","Shock Resistance":"Semi-sinusoidal a = 6 m/s2 at 10 ms; 3 pos. and 3 neg.
