What this MCCB does in the panel
The 4P configuration with neutral left suits panel layouts where the neutral is switched and isolated alongside the phases.
Mounting and connections — what fits
At 108 mm wide by 137 mm high by 80 mm deep, it takes 12 module pitches of 9 mm each on a DIN rail. The Everlink terminals accept 2.5 to 95 mm² rigid or stranded aluminium/copper, or 2.5 to 70 mm² flexible copper — enough for the 25 A feed without fighting oversized lugs. Connection pitch is 35 mm with spreaders, 27 mm without. IK07 impact rating means it survives a knock from a dropped tool during commissioning.
Durability and service life
Rated 20,000 mechanical cycles and 20,000 electrical cycles at 440 V at half rated current, dropping to 10,000 at full current and 5,000 at 690 V. That's a solid lifespan for a distribution MCCB in a panel that sees regular switching — not a disconnect that lives in one position for years.
