For a panel that runs warm — say 50 °C inside the enclosure — the breaker handles about 55 A continuously without tripping on thermal overload. Width is 18 mm — one modular unit (1 MW) on a DIN rail.","metaTitle":"Siemens 5SY4163-8 SENTRON 1-Pole MCB, D Curve, 63 A, 10 kA","metaDescription":"Siemens 5SY4163-8 SENTRON 1-pole MCB, D tripping characteristic, 63 A rated current, 10 kA breaking capacity per EN 60898.
