At 63 A, this is a main or heavy-feeder MCB — not a final-subcircuit device. Width is 18 mm (1 modular width unit), so it occupies a single 18 mm DIN-rail slot. Mounting position is unrestricted. ## Integration notes Power dissipation is 5.4 W per pole in hot operating state at rated current — total 21.6 W for the 4-pole unit. Factor this into enclosure thermal calculations to avoid nuisance tripping from ambient heating inside a crowded panel.","metaTitle":"Siemens 5SL4463-7RC SENTRON MCB, 4P C-Curve 63A 10kA","metaDescription":"Siemens 5SL4463-7RC SENTRON miniature circuit breaker, 4-pole, C-curve, 63 A, 10 kA per EN 60898, 415 V AC.
