The interrupting rating sits at 6 kA at 277 VAC and 10 kA at 125 VDC, which covers most branch-circuit fault levels in a typical industrial control panel.
The C-curve (5–10x In magnetic trip) is the standard choice for moderate inrush loads — think small motors, contactor coils, or lighting banks — where the start surge is higher than a B-curve can tolerate but not as high as a D-curve would need. That's enough for most secondary panel distribution, but if your transformer impedance or utility fault current pushes past 6 kA, you'll need a current-limiting upstream device.
DIN rail integration
The 2-pole footprint takes up two module widths (about 36 mm). In a dense panel, that's compact enough to leave room for a contactor or relay alongside.
