That dual rating covers installations from residential distribution boards to industrial panel feeders. ## Thermal derating and environmental limits The 0.3 A rating holds at 30 °C ambient; at 40 °C it derates to 0.28 A, and at 55 °C to 0.26 A. If the panel runs warm — say, adjacent to a drive or transformer — use the 55 °C figure for sizing. The breaker is rated for any mounting position, which simplifies layout in crowded enclosures. Pollution degree 2 (non-conductive dust, occasional condensation) covers most clean industrial and residential environments. ## Panel integration and compliance It's sealable, halogen-free, silicon-free, and provides touch protection on the terminals.","metaTitle":"Siemens 5SL4414-8 SENTRON MCB, D Curve, 0.3 A, 4 Pole, 10 kA","metaDescription":"Siemens 5SL4414-8 SENTRON miniature circuit breaker, D tripping characteristic, 0.3 A rated, 4-pole, 10 kA breaking capacity per EN 60898 & IEC 60947-2.
