The C-curve means it trips between 5 and 10 times rated current — the standard choice for motor circuits, transformers, and general industrial loads where inrush is moderate. The 4-pole design (4P) switches all three phases plus neutral, so it's the right fit for three-phase distribution subfeeds or machine infeed panels where you need full isolation on all conductors. Rated 63 A at 35 °C ambient, it derates to 60.04 A at 40 °C and 56.89 A at 50 °C — a standard thermal curve that matters when the breaker lives inside a warm enclosure or near other heat sources. The 10 kA SCCR at 400 V AC (per EN 60898) is enough for most secondary distribution panels; if your available fault current is higher, you'll need an upstream current-limiting device or a higher-rated breaker. Designed for railway applications (per the product designation) and rated for mechanical engineering and industry use. Pollution degree 3 and overvoltage category III mean it's rated for the industrial panel environment — not just clean residential switchgear. ## Mounting and integration — panel fit Snaps onto DIN rail via the quick assembly system; 4 modular width units (72 mm wide) occupy standard 18 mm-per-pole spacing. Installation depth is 70 mm; overall depth is 76 mm. Mounting position is any orientation, which simplifies layout in tight enclosures. The combined terminal (top and bottom) accepts conductors without special adapters, and touch protection is integral. Sealable (provision for a lead seal or lockout tag), halogen-free and silicon-free construction — relevant for clean-room or food-grade zones where outgassing or contamination is a concern. IP20 with connected conductors, so it's panel-internal only; no washdown rating.","metaTitle":"Siemens 5SY4463-7CC11 SENTRON MCB, 63A 4P C-Curve, 10kA","metaDescription":"Siemens 5SY4463-7CC11 SENTRON miniature circuit breaker, 63A rated, 4-pole, C-curve, 10kA breaking capacity per EN 60898.
