Breaking capacity is 10 kA per EN 60898 and 15 kA per IEC 60947-2, so it handles standard industrial fault levels up to those thresholds without welding contacts. Rated for 400 V AC at 50/60 Hz, pollution degree 3, overvoltage category III — fits distribution boards in industrial control panels and machinery enclosures. Width is 18 mm (1 modular unit), depth 76 mm, installation depth 70 mm. Sealable, halogen-free, silicon-free — suited for environments where outgassing or contamination matters, such as clean rooms or sealed enclosures. ## Temperature derating Current rating drops with ambient temperature: 59.16 A at 40 °C, 57.14 A at 45 °C, 55.06 A at 50 °C, 52.92 A at 55 °C, 50.65 A at 60 °C. If your panel runs hot, size the upstream protection accordingly. Operating range spans -40 °C to 75 °C, with humidity limits of 95% up to 55 °C, then derated to 35% at 75 °C.","metaTitle":"Siemens SENTRON 5SY4163-5 MCB, 1P, 63 A, Char A, 10/15 kA","metaDescription":"Siemens SENTRON 5SY4163-5 miniature circuit breaker, 1-pole, 63 A rated at 35 °C, tripping characteristic A, 10 kA per EN 60898, 15 kA per IEC 60947-2.
