This covers standard 400 V three-phase distribution in European and IEC-based panels. The 4-pole configuration (3 phases + neutral) suits it for three-phase loads where the neutral must be switched and protected together.
Installation depth is 92 mm; verify enclosure depth before committing the panel layout. Tunnel terminals at both top and bottom accept conductors. The breaker is sealable for panel-lockout programs. IP20 with connected conductors is the standard protection; the handle area can reach IP40 when a distribution cover is fitted.
Mechanical and environmental endurance
Rated for 20 000 mechanical switching cycles typical — sufficient for most distribution and motor-branch applications where the breaker operates infrequently (manual isolation, fault clearing). Shock resistance is 150 m/s² at 11 ms half-sine per IEC 60068-2-27; vibration resistance is 50 m/s² at 25 to 150 Hz and 60 m/s² at 35 Hz (4 sec) per IEC 60068-2-6. These ratings confirm suitability for installation on machinery or in transport applications. Environmental tolerance includes periodically +55 °C with max. 95% humidity — typical for non-condensing industrial enclosures near washdown areas.
