Terminal torque spec is 2.5 to 3.5 N·m — don't overtighten, the screw terminals accept solid or stranded up to 35 mm². ## DIN rail footprint and wiring constraints That's a standard 4-pole MCB footprint — drops into any DIN-rail enclosure with 4 module spaces. Sealable, with touch protection on the terminals. Humidity derating applies above 55 °C per the spec table. ## Approvals and compliance signals Rated per EN 60898 at 6 kA, per UL 1077 and CSA C22.2 No.235 at 5 kA. Overvoltage category III. Energy limiting class 3. Halogen-free and silicon-free construction. Designation per DIN EN 61346-2 and DIN EN 81346-2 is F. The 5SY6CC design variant is the specific internal construction for this order code.","metaTitle":"Siemens 5SY6463-6CC SENTRON MCB, 63A 4P B-curve, 6kA","metaDescription":"Siemens 5SY6463-6CC SENTRON miniature circuit breaker, 63 A, 4-pole, B characteristic, 6 kA breaking capacity per EN 60898.
