That dual rating means the same part passes a 10 kA SCCR check in a domestic board and a 15 kA fault in an industrial sub-panel — one BOM line, two compliance boxes ticked.
One modular width unit at 18 mm wide, so it occupies a single slot in a distribution board. Depth is 70 mm, which clears most shallow enclosures; height is 121 mm.
Halogen-free and silicon-free construction, so no corrosive off-gassing in sealed enclosures.
10 kA per EN 60898 and 15 kA per IEC 60947-2. The higher IEC figure applies in industrial distribution panels.
Width 18 mm (1 modular unit), depth 70 mm, height 121 mm. Snaps onto standard 35 mm DIN rail.
C-curve trips at 5 to 10 times rated current. It handles moderate inrush from motor starters, lighting, and small transformers without nuisance tripping.
