Rated 0.3 A at 35 °C with a C tripping characteristic, it is sized for protecting control transformers, signal-conditioning modules, or small auxiliary circuits — not motor or general-power loads. Breaking capacity is dual-rated: 10 kA per EN 60898-1 for domestic/commercial distribution boards, and 35 kA per IEC 60947-2 for industrial panel applications where higher fault current is available. Current derating is published across the operating range: 0.3 A at 35 °C, 0.28 A at 40 °C, 0.27 A at 45 °C, 0.26 A at 50 °C, 0.25 A at 55 °C, and 0.24 A at 60 °C. Ambient temperature inside a sealed panel often runs 10–15 °C above room temperature, so the 40 °C or 50 °C column is the one to size against for a real installation. Occupies 2 modular width units (36 mm) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm behind the panel face. Neutral conductor is switched (1P+N design), so the neutral is disconnected when the breaker is off, which matters for isolation of single-phase control circuits. Rated to IEC/EN 60898-1 and IEC/EN 60947-2 / UL1077, covering both the domestic MCB standard and the industrial circuit-breaker standard. Halogen-free and silicon-free construction. Humidity limits: max 95% RH up to 55 °C, derating to 35% RH at 75 °C.","metaTitle":"Siemens 5SY4514-7 SENTRON MCB, C-Char 0.3A, 10kA/35kA","metaDescription":"Siemens 5SY4514-7 SENTRON miniature circuit breaker, 1P+N, C characteristic, 0.3 A rated current, 10 kA (EN 60898) / 35 kA (IEC 60947-2) breaking capacity.
