The C-curve (magnetic tripping at 8 x In ±20 %) means it handles moderate inrush — typical for lighting, socket circuits, and small motor loads — without nuisance trips. The 42 kA Icu at 12-133 V AC (EN/IEC 60947-2) is the maximum fault current it can safely interrupt; at 380-415 V AC that drops to 15 kA Icu, and under the domestic standard (EN/IEC 60898-1) the Icn is 10 kA at 400 V AC. For a distribution board feeding mixed loads, this breaker covers both the higher SCCR needed at low voltage and the standard 10 kA domestic rating.
Deployment context
Snaps onto DIN rail (mounting support: DIN rail per). Terminals accept 1-35 mm² rigid or 1-25 mm² flexible, double terminal top and bottom — useful for daisy-chaining or paralleling feeds. IP20 finger-safe protection; suitable for dry indoor panels only, not washdown areas.
