The 5SY6025-6KV: The B-curve trips between 3 and 5 times rated current (75–125A), making it the right choice for resistive and general-purpose loads where inrush is modest — lighting circuits, small transformers, control transformers. The 25A rating handles continuous loads up to that current, derated per the ambient temperature curve. The 1+N-pole configuration switches both line and neutral, with the neutral pole switching but not protecting — common in single-phase final subcircuits where neutral isolation is required. The 70mm installation depth fits standard DIN-rail enclosures, and the single width unit (18mm) keeps panel density tight.
