Mounts on standard DIN rail, takes up 3 width units (54 mm), and the IP20 finger-safe terminals accept solid or stranded conductors from 0.75 to 25 mm².
Terminal and mounting detail
Solid and stranded wire both accepted in the 0.75–25 mm² range.
Coordination and compliance
Energy limiting class 3, overvoltage category III — this breaker limits let-through energy enough for selective coordination with downstream devices in a typical distribution board. It's rated for residential buildings and infrastructure per the manufacturer's suitability listing. The 10 kA SCCR at 400 V matches the standard utility fault level for most European and Asian installations. No neutral pole switching on this 3P unit.
