The 10 A rating sets the continuous current it carries without tripping; the K curve means it tolerates brief inrush currents 8–12× the rating, making it a common pick for motor and transformer branch circuits where nuisance tripping on startup is the concern. Mounts on standard DIN rail, so it clips into any 35 mm rail in the panel. Single-pole format keeps the width to one module — handy when panel space is tight and you only need line-side protection on a single-phase load.
