Its D tripping characteristic (10–20× In magnetic trip) handles high inrush loads like motors, transformers, and solenoid banks without nuisance trips — the 3 A rating is sized for smaller inductive circuits, not general lighting or resistive loads. The 10 kA breaking capacity per EN 60898 (5 kA per UL 1077/CSA C22.2 No.235) covers most industrial panel fault levels; the 1P+N configuration switches the phase and switches the neutral, which matters when you need neutral isolation in a single-module footprint.
Mounting and wiring — the panel-builder's read
Snaps onto DIN rail via the quick-assembly system — 36 mm wide (2 width units), 90 mm tall, 76 mm deep with 70 mm installation depth behind the panel. Tightening torque 2.5–3.5 N·m. Sealable cover option is present if the spec calls for lockout/tagout. Mounting position any; ambient -25 to +55 °C, storage -40 to +75 °C.
