The 1-pole, 1-width-unit (roughly 18 mm per DIN rail module) form factor with 70 mm installation depth snaps into any standard DIN-rail enclosure. Mounting position is unrestricted, which helps in tight panels. Touch protection is built in, so accidental contact with live terminals is prevented when the breaker is properly installed. Energy limiting class 3 gives good current limitation on short circuits, reducing let-through energy to downstream equipment. Vibration resistance is tested to IEC 60068-2-6 at 50 m/s² from 25 to 150 Hz and 60 m/s² from 10 to 150 Hz, so it holds up on machinery or in transport applications. Rated frequency is 50 Hz; the AC/DC voltage type means it can switch DC circuits up to 60 V, though the DC breaking capacity derates — verify coordination for DC loads. Insulation voltage is 440 V AC, and multi-phase operation is rated to 440 V AC maximum. Mechanical service life is 20 000 switching cycles typical.","metaTitle":"Siemens SENTRON 5SJ6163-6 MCB, 1-pole B-curve 63A 6kA","metaDescription":"Siemens SENTRON 5SJ6163-6 miniature circuit breaker, 1-pole, B-curve, 63A, 6kA breaking capacity per EN 60898/IEC 60947-2.
