It snaps onto a DIN rail (REG) and fits a 60 mm grid spacing, occupying 4 modular width units.
The top or bottom supply feed gives flexibility in panel layout. IP20 rating applies once the distribution board is installed with conductors connected — standard for enclosed panel gear. The short-time delay feature (switching function short-term delayed) prevents nuisance tripping from transient leakage currents, which is useful on circuits with motor drives or switching power supplies that generate brief inrush leakage.
The 230/400 V AC supply voltage at 50/60 Hz covers standard European and many international panel voltages. Silicon-free construction is noted for environments sensitive to silicone outgassing.
