The Siemens 5SL4663-8CC is a 3+N-pole miniature circuit breaker rated 400 V with a 10 kA breaking capacity and a D tripping characteristic at 63 A. The D-curve means it handles inrush currents typical of motor and transformer loads without nuisance tripping — the magnetic trip operates at 10–20× In, so it's sized for circuits where the startup surge is well above the running current. This part is in the Basic Devices family and carries the group code P310 (product group 3824). It's a standard DIN-rail mount MCB for panel integration, with the 3+N configuration providing overcurrent protection on all three phases plus a switched neutral.
