Rated operating voltage is 400 V AC (440 V max single- or multi-phase), with a DC rating up to 72 V. Snap-on quick assembly and any mounting position simplify panel integration — no special orientation required. ## Selection and coordination notes The 6 kA rated short-circuit capacity per EN 60898 defines its fault-clearing capability at 400 V AC. For UL-listed panels, the 5 kA rating per UL 1077 applies — verify SCCR coordination with upstream protective devices. The C-trip characteristic is the key selection parameter: it allows short-duration inrush up to 10× rated current without nuisance tripping, making it the standard choice for motor control circuits, contactor coils, and lighting with electronic ballasts. If the load is purely resistive with no inrush, a B-curve MCB would provide faster fault response; if high inrush (transformers, large motors), a D-curve may be needed. The 5SY6363-7CC sits in the middle — the most common industrial choice. Halogen-free and silicon-free construction reduces corrosive gas emission in a fault — important for panels housing sensitive electronics. Sealable to prevent unauthorized access to the trip setting or terminal area. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz. Mechanical service life 10 000 operating cycles typical.","metaTitle":"Siemens 5SY6363-7CC SENTRON MCB, 3P C-Curve, 6 kA, 400 V","metaDescription":"Siemens SENTRON 5SY6363-7CC 3-pole miniature circuit breaker, C-trip characteristic, 6 kA per EN 60898, 400 V AC, 72 V DC max.
