Breaking capacity hits 25 kA per IEC 60947-2 and 15 kA on the DC side; UL 1077 listing drops to 5 kA. Snap-mounts via the quick assembly system into any standard DIN-rail enclosure; any mounting position works. The 3-module-width footprint (54 mm) and 76 mm depth fit standard 18 mm pitch rails — no panel rework needed. Vibration resistance per IEC 60068-2-6 (±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz) means it holds up on machinery with moderate vibration. Current production — no phase-out notice on record. Backed by IEC/EN 60947-2 and UL 1077 approvals. Halogen-free and silicon-free construction; sealable for lockout/tagout. Rated for mechanical engineering and industry applications per the suitability listing. ## Integration — panel fit Combined top and bottom terminals simplify busbar and load-side wiring. Neutral conductor switching is not integrated — use a separate switched neutral bar if the circuit requires it. Supply cord position is any, so feed from top or bottom as the layout demands. Installation depth is 70 mm, leaving clearance behind the DIN rail.","metaTitle":"Siemens 5SY8363-7 SENTRON MCB, 3P C-Curve, 25 kA IEC","metaDescription":"Siemens 5SY8363-7 SENTRON miniature circuit breaker, 3-pole, C-curve, 25 kA breaking capacity per IEC 60947-2, 5 kA UL 1077.
