Its 20 kA breaking capacity per IEC 60947-2 gives you headroom for high-fault industrial panels — that's the figure that governs selectivity coordination downstream, not the UL 1077 5 kA rating, which is a separate listing for North American branch-circuit recognition. The C-curve trips magnetically between 5 and 10 times rated current — 315 to 630 A instantaneous — so it's sized for motor-starting inrush or transformer magnetizing currents where a B-curve would nuisance-trip. At 63 A continuous it handles a 30–35 kW motor load on 400 V three-phase, but watch the ambient derating: the breaker is rated for -25 to +55 °C ambient, and above 40 °C the thermal trip shifts earlier. For UL 508A panels the 5 kA per UL 1077 is the binding number; if your assembly requires a higher AIC, you'll need a current-limiting upstream device. Terminals accept 0.75 to 35 mm² solid or stranded with a torque spec of 2.5 to 3.5 N·m — that's a standard screw-terminal range that covers most panel wiring from 14 AWG to 2 AWG. The 72 mm width occupies 4 width units at 18 mm each, so plan for that footprint in your panel layout. Depth is 76 mm with an installation depth of 70 mm behind the panel face; the 90 mm height leaves room for a gland plate above. Sealable lets you lock the toggle position with a wire or padlock for lockout/tagout.","metaTitle":"Siemens 5SY7463-7CC SENTRON MCB, 63A 4P C-Curve, 20kA IEC","metaDescription":"Siemens SENTRON 5SY7463-7CC miniature circuit breaker, 63 A, 4-pole, C characteristic, 400 V AC, 20 kA IEC breaking capacity.
