Breaking capacity is 15 kA per IEC 60898 and IEC 60947-2, with a separate 5 kA rating under UL 1077 and CSA C22.2 No.235 — the UL figure governs installations in North American control panels where the available fault current stays under 5 kA; the 15 kA IEC figure applies in European distribution boards. Two-pole 1P+N configuration switches both line and neutral, with the neutral pole switching but not protecting — the overcurrent trip acts only on the phase conductor. Rated for overvoltage category III, so it's suited for fixed-installation downstream of the utility meter. Width is 36 mm (2 width units), depth 76 mm, height 90 mm — snaps onto standard 35 mm DIN rail via the quick-assembly system. Installation depth 70 mm leaves clearance behind the rail for wiring. Mounting position any, so vertical or horizontal orientation in the panel is fine. IP20 with conductors connected — open-front protection only; keep live terminals behind a panel door or cover. Sealable enclosure option and touch protection built in. Halogen-free and silicon-free construction, so it won't outgas corrosive compounds in sealed enclosures or near sensitive electronics. Ambient temperature range -40 to +70 °C, with humidity derating above 55 °C: max 95% RH up to 55 °C, then 55% RH at 70 °C, then 35% RH at 75 °C. Storage range -40 to +75 °C covers warehouse and transport extremes. Functional letter per DIN EN 61346-2 and DIN EN 81346-2 is F — protective device. Suitable for mechanical engineering and industry applications per the manufacturer's classification.","metaTitle":"Siemens 5SY7563-8 SENTRON MCB, 63A D Curve, 2-Pole, 15kA","metaDescription":"Siemens 5SY7563-8 SENTRON miniature circuit breaker, 63 A rated current, D tripping characteristic, 2-pole 1P+N, 15 kA breaking capacity per IEC 60898.
