The C-curve is the right choice here because a pure resistive load (heater, indicator lamp) would be fine on B-curve, but rail auxiliary panels often have a small transformer or a DC/DC converter input that pulls a brief inrush. ## Deployment context The 4-pole width (4 modules at 18 mm each) fits a standard rail distribution board inside a locomotive electrical cabinet or a trackside signal enclosure. The railway application marking on the order code means the breaker carries the vibration, shock, and temperature cycling qualification per EN 61373 and EN 50155 — not every 10 kA MCB on the shelf has that, so if you're replacing a part in a rail-certified panel, this is the one that keeps the type approval intact.","metaTitle":"Siemens 5SY4414-7CC11 MCB, 400V 10kA, 4P, C-curve, 0.3A, rai","metaDescription":"Siemens 5SY4414-7CC11 miniature circuit breaker, 400V 10kA, 4-pole, C-curve, 0.3A, for railway applications.
