The 60 kA Icu at 220/240 V AC tells you the maximum fault current it can safely interrupt at that voltage level; at 380/400 V AC the breaking capacity drops to 30 kA Icu, which is the number you coordinate with your upstream protection.
Fixed mounting on a backplate, front-connected both line and load sides. The 25 mm connection pitch matches standard busbar spacing for panelboard integration. Dimensions are 130 mm high, 75 mm wide, 60 mm deep — that 75 mm width is a three-pole footprint that fits a standard distribution panel cutout. Neutral position is left. IP40 enclosure protection keeps out tools and wires over 1 mm; IK07 impact resistance handles light mechanical shock during installation.
