No ground-fault detection on this variant, so that's handled separately if the application requires it.
Width is 45 mm — three 9 mm pole pitches — so it occupies a standard 45 mm slot on a DIN rail. Depth is 75 mm, height 90 mm. Clearance requirements: 20 mm upwards, 20 mm downwards, 9 mm to the side, zero forwards or backwards. That's tight enough to pack breakers side-by-side without worrying about arc flash gaps — just the 9 mm side clearance. Terminals are M3 screw-type for the main circuit, accepting 2×(0.5…1.5 mm²) or 2×(0.75…2.5 mm²) solid or stranded. No special tools needed beyond a standard screwdriver.
