B-curve trips between 3 and 5 times rated current — 189 to 315 A at 63 A. The 63 A rating is the continuous thermal current at 50/60 Hz; at elevated ambient temperature the breaker derates per the influence curve (max 95% RH at 55 °C, dropping to 35% RH at 75 °C). Width is 18 mm — one modular unit on a standard DIN rail. Mounting position any, which simplifies tight gland-plate layouts.","metaTitle":"Siemens 5SY6163-6 SENTRON MCB, 1P B-Curve 63 A 6/10 kA","metaDescription":"Siemens 5SY6163-6 SENTRON miniature circuit breaker, 1-pole, B-curve, 63 A rated current, 6 kA (EN 60898) / 10 kA (IEC 60947-2) breaking capacity, 18 mm wide.
