Sizing and fit for the panel
At 45 mm wide and 97 mm deep, this breaker occupies a single 45 mm slot on the DIN rail. The 106 mm height leaves clearance for busbar connections above and below. Clearance requirements: 50 mm above and below, 30 mm to the side, 0 mm forward and backward — so it can be stacked tightly in a multi-row enclosure as long as vertical air gaps are maintained. No screwdriver torque check needed on the power connections — the spring clamp holds consistently across the wire range.
