It connects the main circuit via spring-loaded terminals (cage clamp style) accepting solid or stranded wire from 4 mm² up to 35 mm², with a stripped length of 23 mm for the main contacts. The spring termination saves panel wiring time compared to screw clamps — no torque driver needed, just push the stripped conductor in. ## Panel fit and mounting flexibility At 27 mm wide, 154 mm tall, and 107 mm deep, this infeed block occupies a single DIN-rail slot — important when packing multiple motor feeders into a control cabinet. The fastening method allows both screw fixing and snap-on mounting to the DIN rail, giving the panel builder a choice between permanent screw-down in high-vibration environments or quick clip-on for standard enclosures. The design supports infeed from either the left or right side, which simplifies busbar routing in a multi-feeder lineup. Pollution degree 3 rating means it tolerates conductive dust and humidity typical of industrial floors without creepage failure. ## Environmental and mechanical qualification The shock resistance is specified at 6 m/s² semi-sinusoidal for 10 ms in all three axes, and vibration resistance covers 4–500 Hz at 2 m/s² — numbers that match machine-mounted or conveyor-line installations where the panel sees floor-borne vibration. Installation altitude is limited to 2000 m above sea level without derating — standard for low-voltage switchgear. Above that, consult the derating guidelines in the SIRIUS system manual.","metaTitle":"Siemens 3RA6830-5AC SIRIUS Infeed, 63 A at 400 V AC-3","metaDescription":"Siemens 3RA6830-5AC SIRIUS infeed block, 63 A AC-3 at 400 V, spring-loaded terminals, 27 mm wide, active production.
