Product details

The Siemens 5SL4463-6CC is a 4-pole miniature circuit breaker rated for 400 V AC with a 10 kA breaking capacity, B-curve trip characteristic, and 63 A rated current. It belongs to the Basic Devices product family and carries group code P310, product group 3822.

The B-curve (3-5× In magnetic trip) is standard for resistive and general-purpose loads; it avoids nuisance tripping on moderate inrush while still clearing fast on hard faults. The 4-pole configuration (3 phases + neutral switched) is typical for three-phase final subcircuits in IEC markets.

Deployment context

Snap-on DIN rail mounting for standard 35 mm rail in panel enclosures. Four-pole switching covers three-phase plus neutral disconnection.
