Under UL 1077 and CSA C22.2 No. 235, the breaker is rated at 5 kA, confirming its suitability for North American supplementary protection applications. The quick-assembly system allows ganging with other SENTRON devices without extra hardware. The sealable design allows lockout/tagout for maintenance isolation. ## Environmental and lifecycle Rated for ambient temperatures from -40 °C to +75 °C, with derating of the humidity tolerance at higher temperatures: 95% RH up to 55 °C, 55% RH up to 70 °C, and 35% RH up to 75 °C. Vibration resistance per IEC 60068-2-6 covers ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz — adequate for installation on machine-mounted panels. Power loss per pole at rated current is 4.4 W, so total dissipation for the 4-pole unit at full load is about 17.6 W — factor that into enclosure thermal calculations. ## Sourcing and compliance This part is specified for mechanical engineering and industrial applications per the manufacturer's suitability designation. The 5SY7463-8CC carries IEC 60947-2 certification for the 15 kA rating and UL 1077 / CSA C22.2 No. 235 for the 5 kA rating.","metaTitle":"Siemens 5SY7463-8CC SENTRON MCB, 4P D 63A 400V 15kA","metaDescription":"Siemens SENTRON 5SY7463-8CC miniature circuit breaker, 4-pole, D-curve, 63 A, 400 V AC, 15 kA breaking capacity per IEC 60947-2.
