At 40 °C ambient the 63 A rating derates to 59.98 A; at 50 °C it drops to 56.83 A. That derating curve is the real selection number for a crowded enclosure, not the 63 A nameplate. The 6 kA rating under EN 60898 covers most final subcircuits; the 10 kA under IEC 60947-2 gives headroom for higher-fault industrial panels. Any mounting position allowed. Current production — no obsolescence notice on record. The 5SY6363-6 is an active catalog line within the SENTRON range. ## Compliance and material notes Sealable (can be locked in OFF position for lockout/tagout). Energy limitation class 3, meaning it limits let-through energy to a low level during a short-circuit, reducing stress on downstream components.","metaTitle":"Siemens 5SY6363-6 SENTRON MCB, 63 A, 3P, B-Curve, 6/10 kA","metaDescription":"Siemens SENTRON 5SY6363-6 miniature circuit breaker, 63 A rated, 3-pole, B characteristic, 6 kA per EN 60898 / 10 kA per IEC 60947-2.
