Mounting, wiring, and panel fit
At 54 mm wide (3 width units), it occupies three 18 mm module spaces on the rail. The 76 mm depth and 70 mm installation depth mean it fits standard 80 mm deep enclosures with clearance for wiring. Wire range accepts 0.75 to 35 mm² solid or stranded copper — that covers everything from control-circuit tails up to the main feeder for a 50 A subpanel. Combined terminals top and bottom allow busbar feed-through or daisy-chaining. Tightening torque is 2.5 to 3.5 N·m; a torque screwdriver is worth the time to avoid terminal heating.
