It protects a single-phase final subcircuit against overload, short-circuit (B curve, 3–5× In magnetic trip), and earth leakage at 300 mA sensitivity.
DIN-rail fit and panel integration
The neutral is on the left, phase on the right — verify busbar orientation before snapping it in. IP20 on the body, IP40 inside a modular enclosure. Terminal accepts 1–16 mm² rigid or 1–10 mm² flexible; strip 15 mm, torque to 2 N·m.
