It's a magnetic-only trip design — no thermal element — so it responds purely to overcurrent, not to sustained low-level overloads. That makes it a fit for applications where you want short-circuit protection but handle overloads separately (e.g., via a motor-protective relay). ## Compliance and approvals Rated per IEC 60947-2 (30 kA) and also carries a UL 1077 / CSA C22.2 No. 235 rating of 5 kA — that's the supplementary-protector rating for North American panels where the MCB is used as a branch-circuit component, not a main. Halogen-free and silicon-free construction, sealable, with touch protection on the terminals. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz.","metaTitle":"Siemens 5SY8216-8BB08 SENTRON MCB, 2-pole 16A D-curve, 30kA","metaDescription":"Siemens SENTRON 5SY8216-8BB08 miniature circuit breaker, 2-pole, 16 A, D characteristic, 30 kA IEC 60947-2.
