Touch protection is built in. ## Compliance and approvals The 5SY8632-8 carries a UL 1077 and CSA C22.2 No. 235 supplementary protector listing at 5 kA — enough for North American panel applications where a full UL 489 branch breaker isn't required. Halogen-free and silicon-free construction, sealable for lockout/tagout. Vibration resistance per IEC 60068-2-6 covers ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz.","metaTitle":"Siemens 5SY8632-8 SENTRON MCB, 4P D 32A 30kA IEC","metaDescription":"Siemens 5SY8632-8 SENTRON miniature circuit breaker, 4-pole 3P+N, D characteristic, 32 A, 30 kA IEC 60947-2, IP20, halogen-free.
