The 0.3 A rating at 35 °C is the continuous current the breaker carries without tripping; derate to 0.29 A at 40 °C, 0.28 A at 45 °C, 0.27 A at 50 °C, 0.26 A at 55 °C, and 0.25 A at 60 °C if the panel ambient runs warm. The 10 kA SCCR per EN 60898 is the standard for final circuits in residential and commercial distribution boards; the 35 kA per IEC 60947-2 applies when the breaker is used in industrial switchgear where higher prospective fault currents are possible. ## Panel integration Halogen-free and silicon-free construction suits environments where outgassing must be minimized — clean rooms, medical, or telecom shelters.","metaTitle":"Siemens 5SY4614-7 SENTRON MCB, 4-Pole C-Curve 0.3A, 10kA","metaDescription":"Siemens 5SY4614-7 SENTRON miniature circuit breaker, 4-pole (3P+N), C-curve, 0.3 A rated at 35 °C, 10 kA breaking capacity per EN 60898, 35 kA per IEC 60947-2.
