Integration notes for the panel builder
The 4-pole form factor (3 poles + switched neutral) occupies four DIN-rail module widths in a standard 35 mm enclosure — account for the fill factor when laying out a rail with adjacent breakers or auxiliaries. Rated for 400 V line-to-line, so it suits both 230/400 V three-phase rail auxiliary networks and single-phase 230 V branch circuits when the neutral pole is used as the switched pole.
