It delivers a 15 kA breaking capacity per IEC 60898 and 25 kA per IEC 60947-2, making it suitable for high-inrush loads like motor circuits and transformers where the D curve avoids nuisance tripping on startup. The 15 kA rating under IEC 60898 covers standard domestic/commercial fault levels, while the 25 kA under IEC 60947-2 gives headroom for industrial panels with higher prospective short-circuit currents. The D curve (10–20× In) is the key difference from a C-curve sibling — it handles the magnetizing inrush of motors, welders, or UPS systems without dropping the load. ## Environmental range and derating Rated for ambient temperatures from -40 °C to 75 °C, with a derating curve provided: at 45 °C the continuous current drops to 14.51 A, at 50 °C to 13.98 A, at 55 °C to 13.44 A, and at 60 °C to 12.86 A.","metaTitle":"Siemens SENTRON 5SY7216-8 MCB, D Curve, 16 A, 2-Pole, 15 kA","metaDescription":"Siemens SENTRON 5SY7216-8 miniature circuit breaker, D tripping characteristic, 16 A at 35 °C, 2-pole, 400 V AC, 15 kA (IEC 60898) / 25 kA (IEC 60947-2).
