The Siemens 5SY4563-8 is a SENTRON miniature circuit breaker rated 63 A at 230 V AC, with a D tripping characteristic and 2 poles configured as 1P+N. For UL 1077 / CSA C22.2 No. 235 installations, the interrupting rating is 5 kA.
Snaps onto DIN rail via the quick-assembly system — 36 mm wide (2 width units), 90 mm tall, 76 mm deep, with an installation depth of 70 mm.
Both solid and stranded conductors from 0.75 mm² up to 35 mm². The combined top and bottom terminals handle that range without adapters.
Both are SENTRON 5SY-series MCBs with the same 36 mm width, DIN-rail mounting, and terminal ranges, so the physical footprint and wiring are identical. The difference is electrical: the 5SY4563-8 is a 63 A D-curve 1P+N breaker, while the 5SY3132-6 is a different rating and characteristic. Check the downstream load and coordination study before swapping.
