The D-curve characteristic (10–20× In) handles high inrush loads like traction converters and auxiliary transformers without nuisance tripping — that's the curve you want when the load is inductive or capacitive, not resistive. The 1+N configuration switches both line and neutral, with overcurrent protection on the line pole only. ## Integration into a panel The 1+N width occupies two modular spaces (36 mm). For railway applications, verify the terminal screws are tightened to the vibration-resistant specification in the installation manual; the standard DIN-rail clip holds under the shock and vibration profile of EN 61373.","metaTitle":"Siemens 5SY4563-8CC11 MCB, 230V 10kA, 1+N D 63A, Railway","metaDescription":"Siemens 5SY4563-8CC11 miniature circuit breaker, 230V 10kA, 1+N-pole, D-curve, 63A for railway applications.
