This D-curve is designed for high inrush loads — motors, transformers, welding equipment — where the magnetic trip holds off until roughly 10–20× rated current, avoiding nuisance trips on startup. ## Thermal derating and environment At 40 °C ambient the continuous rating drops to 15.04 A; at 55 °C it's 13.47 A. The operating range spans -40 °C to 75 °C, with humidity limits of 95% up to 55 °C, 55% to 70 °C, and 35% to 75 °C. Any mounting position is permitted, and the supply cord can enter from any side. The unit is sealable, which allows panel builders to lock the setting after commissioning. No neutral conductor switching — this is a straight 3-pole line breaker.","metaTitle":"Siemens SENTRON 5SY4316-8CC MCB, 16 A, D Curve, 10 kA","metaDescription":"Siemens SENTRON 5SY4316-8CC miniature circuit breaker, 3-pole, 16 A, D tripping characteristic, 10 kA breaking capacity per EN 60898, 440 V AC.
