What the K-curve and 13 A mean for fit
Curve K trips between 8 and 12 times rated current — designed for inductive loads like motor starters, solenoids, and transformer primaries where inrush is high but short-lived. On a 13 A frame, that means magnetic trip between roughly 104 A and 156 A, keeping the breaker from nuisance-tripping on startup while still protecting the cable downstream. On a 2-pole format, it handles single-phase or DC loads cleanly, or two legs of a three-phase circuit with a separate neutral.
The S800C family shares a uniform 2-module width per pole — the S802C-K13 occupies 4 module spaces (roughly 72 mm) on the rail. In an existing panel, verify the busbar comb footprint: the S800C uses a different pin spacing than the S200 series, so a comb bar from an S200 panel will not align without adapter clips.
