The K characteristic means it trips between 10 and 14 times rated current, designed for motor and inductive loads where inrush current is higher than resistive loads — so it holds through a motor start without nuisance tripping but still clears a hard fault.
Panel Integration
Snap-on DIN rail mounting for standard 35 mm rail, common in distribution boards and sub-panels. The 3-pole form factor occupies three module widths; plan for thermal derating when grouping multiple breakers in a closed enclosure.
