The D characteristic provides a higher magnetic trip threshold (10–20× In), sized for loads with high inrush, such as small motors, transformers, or discharge lighting.
Snap-on DIN rail mount for standard 18 mm modular enclosure spacing. The 1+N form factor occupies a single module width, leaving adjacent slots free for other DIN-rail devices. Terminal capacity accepts up to 25 mm² conductor, typical for final subcircuits at this current level.
