The Siemens 5SY6363-8 is a 3-pole miniature circuit breaker from the SENTRON 5SY6 family, rated 63 A at 400 V AC with a D tripping characteristic.
The 5SY6363-8 carries two breaking-capacity ratings: 6 kA under EN 60898 (the residential / light commercial standard) and 10 kA under IEC 60947-2 (the industrial standard). The UL 1077 / CSA C22.2 No.235 rating is 5 kA, which covers North American supplementary-protection applications.
The part is sourced to order through independent distribution. Submit an RFQ; availability and current pricing are confirmed at quote time.
The overall depth is 76 mm; the installation depth (behind the panel face) is 70 mm.
The width is 54 mm, which corresponds to 3 standard DIN-rail module units (18 mm per module).
Both are 3-pole SENTRON MCBs on the same DIN-rail footprint, but the 5SY4140-7 is a B-curve 40 A unit. The 5SY6363-8 is D-curve 63 A — different tripping characteristic and current rating. Mechanical fit is the same; electrical substitution requires a coordination check.
Alternative models and sibling configurations in the same Siemens series. For obsolete or discontinued parts, these models can serve as compatible replacements or functional alternatives for plant maintenance.
