The C-curve (5–10× In) means it handles moderate inrush without nuisance tripping — typical for motor-starter, lighting, and small-transformer circuits where the start-up surge sits below 10 A. Thermal derating is built in: the breaker carries its full 1 A only up to 35 °C. At 40 °C it derates to 0.93 A, at 45 °C to 0.89 A, at 50 °C to 0.8 A, and at 55 °C to 0.8 A. The 2-pole form factor (36 mm wide, 2 modular-width units) switches both phase and neutral — the neutral conductor switching feature is integrated, so no separate neutral block is needed downstream. ## Environmental and compliance specs Rated for ambient temperatures from -40 °C to 75 °C, with humidity limits of 95% RH up to 55 °C, then derating to 35% RH at 75 °C. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz — suitable for installation on machine-mounted sub-panels subject to moderate vibration. Sealable terminals and touch protection are standard. These make it a clean fit for food-and-bev, pharmaceutical, or semiconductor-adjacent panels where outgassing or contamination is a concern.","metaTitle":"Siemens 5SY4501-7CV 2-Pole MCB, C-Curve 1A, 15kA IEC 60947-2","metaDescription":"Siemens 5SY4501-7CV 2-pole miniature circuit breaker, C-curve, 1A rated, 15kA breaking capacity per IEC 60947-2.

That is the rated ultimate short-circuit breaking capacity (Icu) for this 2-pole C-curve breaker."},{"question":"What does the C-curve mean on this breaker?","answer":"The C tripping characteristic (5–10× In) means magnetic trip occurs between 5 A and 10 A for the 1 A rated version. It is designed for circuits with moderate inrush — motor starters, lighting groups, small transformers — where a B-curve would nuisance-trip on startup."},{"question":"Will 5SY4501-7CV fit in a panel designed for 5SY4140-7?","answer":"Both are 2-pole, 36 mm wide (2 MW) Siemens 5SY-series MCBs sharing the same DIN-rail footprint, terminal layout, and 70 mm installation depth. The 5SY4501-7CV drops into the same panel position without rewiring — the difference is the current rating (1 A vs 40 A for the 5SY4140-7) and the tripping curve (C vs B)."},{"question":"What compliance documentation is available for 5SY4501-7CV?","answer":"The breaker is certified to IEC / EN 60947-2, carries CE marking, and is halogen-free and silicon-free.
