The Siemens 5SL6413-8CC is a 4-pole miniature circuit breaker (MCB) rated 400 V with a 6 kA breaking capacity, D-curve trip characteristic, and 13 A current rating. The D-curve means it tolerates high inrush currents typical of motor, transformer, and lighting loads — tripping between 10x and 20x rated current (130 A to 260 A) for short-circuit protection, while the 6 kA interrupting rating at 400 V ensures it can safely clear faults up to that level without upstream damage. This makes it a fit for final subcircuits in industrial control panels where inductive loads are present.
Snap-on DIN rail mounting for standard 35 mm rail. Four-pole form factor occupies 4 module widths (72 mm at 18 mm per pole). Rated for 400 V line-to-line, so it suits three-phase plus neutral circuits in distribution boards or sub-distribution panels.
