What the ratings mean for your panel
The 5SL4402-7CC has a 10 kA breaking capacity at 400 V, as described in the specification. The C-curve (magnetic trip between 5× and 10× In) suits moderate inrush loads like small motor starters, lighting banks, or transformer primaries — it holds through the startup spike without nuisance tripping, unlike a B-curve that would drop on the same surge. Four poles mean it switches all three phases plus neutral, so it fits three-phase 400 VAC sub-distribution where the neutral needs overcurrent protection or isolation alongside the line conductors.
