D-curve 16 A, 4-pole — selectivity for high-inrush loads
The Siemens 5SL6416-8CC is a SENTRON miniature circuit breaker rated 16 A at 400 V AC, 4-pole, with a D tripping characteristic and a 6 kA breaking capacity per EN 60898.
At 30 °C ambient the breaker holds the full 16 A; at 40 °C it derates to 15.28 A, at 45 °C to 14.91 A, at 50 °C to 14.53 A, and at 55 °C to 14.14 A. If the panel runs warm — common in a crowded enclosure — size the load a notch below the 30 °C nameplate. The 4-module width (72 mm) occupies four 18 mm slots on a DIN rail; depth is 76 mm with 70 mm installation depth behind the rail.
