The Siemens SENTRON 5SP9363-7KC47 is a 3-pole miniature circuit breaker rated 63 A with a C tripping characteristic. Its 50 kA breaking capacity at 400 V AC per IEC 60947-2 means it can safely interrupt high fault currents in industrial distribution panels without cascading upstream — that's the spec that decides fit for high-available-fault-current installations like transformer-fed sub-distribution boards. Rated supply voltage is 400 V AC at 50 Hz, with a maximum operating voltage of 440 V AC.
Mounts on standard DIN rail or via screw fixing — the 4.5 width units (about 81 mm) and 92 mm installation depth fit standard SENTRON distribution boards and enclosure cutouts. Tunnel terminals top and bottom accept conductors without ferrules; Sealable, halogen-free, and silicon-free construction suits installations with strict material restrictions — food processing lines or semiconductor fabs where outgassing contaminants can't be tolerated.
