It's a 2-pole unit in a 1P+N design — meaning it switches both the line and neutral conductors, with the neutral pole switching but not protected. That makes it the right choice for single-phase final circuits where you need to isolate the neutral, common in distribution boards across mechanical engineering and industrial panels. The C-curve (tripping characteristic class C) means the magnetic trip operates at 5 to 10 times the rated current — so for this 16 A MCB, instantaneous trip happens between 80 A and 160 A. Temperature derating is built into the spec: it carries the full 16 A up to 35 °C, then drops 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. ## Mounting and integration notes Accepts any mounting position.","metaTitle":"Siemens 5SY6516-7CC SENTRON MCB, C-16A, 6kA, 2-Pole","metaDescription":"Siemens 5SY6516-7CC SENTRON miniature circuit breaker, C-curve, 16A rated, 6kA breaking capacity per EN 60898, 2-pole 1P+N, 36mm wide.
