Breaking capacity is 15 kA per EN 60898 and 20 kA per IEC 60947-2 — the IEC figure governs when used in industrial distribution with higher prospective fault current. Characteristic B trips between 3 and 5 times rated current, so it is sized for resistive or lightly inductive loads where inrush stays moderate — lighting banks, small transformers, control circuits. Mounts on DIN rail via the quick-assembly system in any position. Occupies 3 modular width units (54 mm wide). Depth is 76 mm with 70 mm installation depth behind the panel surface — confirm clearance before laying out a shallow enclosure. IP20 with connected conductors; pollution degree 3 and overvoltage category III suit it for fixed-installation panels in factory environments. Sealable design allows lockout-tagout on the breaker handle. Rated current derates with ambient temperature: 63 A at 35 °C, 59.98 A at 40 °C, 58.4 A at 45 °C, 56.83 A at 50 °C, 55.12 A at 55 °C, 53.42 A at 60 °C. If the panel ambient runs above 40 °C, size the upstream protection for the derated value. Halogen-free and silicon-free construction — no outgassing concerns in clean-room or electronics-adjacent installations. Combined terminals top and bottom accept standard copper conductors.","metaTitle":"Siemens 5SY7363-6 SENTRON MCB, 63 A, 3-Pole, Char B, 15/20 k","metaDescription":"Siemens SENTRON 5SY7363-6 miniature circuit breaker, 63 A, 3-pole, tripping characteristic B, breaking capacity 15 kA per EN 60898 / 20 kA per IEC 60947-2.
