SENTRON 5SY4316-6CC — 3-pole 16 A B-characteristic MCB
For a 16 A breaker on a lighting or general-purpose load circuit, that's the right balance.
Thermal derating and environmental range
Rated 16 A at 35 °C ambient; derate to 15.04 A at 40 °C, 14.54 A at 45 °C, 14.02 A at 50 °C, and 13.47 A at 55 °C. Operating range spans -40 °C to 75 °C, with humidity limits of 95% RH up to 55 °C, 55% RH to 70 °C, and 35% RH to 75 °C.
Approvals and documentation
Listed per EN 60898 for 10 kA breaking capacity and per UL 1077 / CSA C22.2 No. 235 for 5 kA. The UL 1077 listing is as a supplementary protector — it requires an upstream branch-circuit overcurrent device. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz. Halogen-free and silicon-free construction; sealable for tamper-proof installations.
