This is a Category A breaker (no intentional short-time delay), so it is not designed for selectivity with downstream breakers in a cascaded scheme — coordinate it as the main or branch breaker in a radial distribution.
At 108 mm wide × 137 mm high × 80 mm deep, it occupies 12 module pitches of 9 mm — plan your DIN-rail or panel cut-out accordingly. Front connections (both upside and downside) accept Everlink lug terminals: 2.5…95 mm² rigid or stranded aluminium/copper, or 2.5…70 mm² flexible copper. The 35 mm connection pitch (27 mm without spreaders) matches standard busbar systems. The flag indicator (green) shows presence of auxiliary contacts, useful during commissioning to verify contact state without removing the cover.
The breaker carries no integrated earth-leakage protection; if ground-fault detection is required, specify an external residual-current device or a different trip unit variant. Electrical durability is 20,000 cycles at rated current (440 V, In/2) and 10,000 cycles at full In — adequate for distribution duty but not for frequent switching applications.
