The UL 1077 listing gives 5 kA for North American panels. This is a current-production part — no lifecycle change on record. D-curve (10–20× In) is the correct choice for motor, transformer, or welding loads that draw a high inrush without nuisance tripping. At 60 V DC the rating drops to 15 kA; the UL 1077 branch-circuit recognitions sits at 5 kA. The -40 to 75 °C operating range covers cold storage and freezer environments without derating concerns, though the surrounding temperature influence table (95% RH at 55 °C, 55% at 70 °C, 35% at 75 °C) should be checked for high-humidity, high-temp installations. The quick-assembly fastening system and any-position mounting simplify panel layout. IP20 with connected conductors is standard for enclosed panels; the sealable option (lockable toggle) supports lockout/tagout procedures. Vibration resistance per IEC 60068-2-6 is ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz.","metaTitle":"Siemens 5SY8563-8 SENTRON MCB, D-curve, 2-pole, 20 kA","metaDescription":"Siemens 5SY8563-8 SENTRON miniature circuit breaker, D tripping characteristic, 2-pole (1P+N), 20 kA at 230 V AC per IEC 60947-2.
