The fixed instantaneous pickup at 320 A (3.2 x In) means the magnetic trip will clear a short-circuit fault above that level; for generator feeds where inrush is lower than motor starting, this fixed band is usually adequate. The 4D protected poles (neutral fully protected at 1 x Ir) suit 4-wire generator outputs where the neutral carries load current and must be treated as a phase.
