What the ratings mean for fit
The Siemens 5SL4650-7CC is a 3+N-pole miniature circuit breaker rated 400 V with a 10 kA breaking capacity and a C-curve trip characteristic at 50 A. The C-curve means the magnetic trip operates at 5 to 10 times rated current — designed for moderate inrush loads like motor starters, small transformers, and banks of fluorescent lighting where the start-up surge exceeds a B-curve tolerance but stays below the higher thresholds of a D-curve. At 50 A per pole and a 10 kA short-circuit capacity at 400 V, this breaker clears faults up to that level without upstream cascading, making it suitable for sub-distribution boards and final circuits in commercial or light industrial panels.
