The 16 A rating holds only at 35 °C. At 40 °C the breaker must be derated to 15.04 A; at 50 °C it drops to 14.02 A; at 60 °C it is 12.91 A. That derating curve is the number that matters for BOM-fit, not the 35 °C headline. The breaker also carries a humidity derating: max 95% RH up to 55 °C, dropping to 35% RH at 75 °C, which governs sealed or outdoor enclosures in tropical climates. Occupies 4 modular width units (72 mm wide, 90 mm tall, 76 mm deep, with an installation depth of 70 mm). Mountable in any position, which simplifies layout in crowded enclosures. The combined terminal design (top and bottom) accepts the same conductor range and tooling, so wiring order does not matter. Touch protection is built in on the terminals, meeting IP20 with connected conductors — safe for finger-probe access in open panels.","metaTitle":"Siemens 5SY4616-8CC11 SENTRON MCB, D Curve, 16 A, 10 kA","metaDescription":"Siemens 5SY4616-8CC11 SENTRON miniature circuit breaker, 4-pole 3P+N, D tripping characteristic, 16 A rated at 35 °C, 10 kA breaking capacity per EN 60898.
