B-curve means it trips at 3–5× rated current — standard for general-purpose socket circuits and lighting in residential buildings and infrastructure where inrush is low.
DIN-rail fit and wiring constraints
Wire range accepts 0.75 to 25 mm² solid or stranded; torque the screw terminals to 2.5–3 N·m.
Neutral switching and environmental limits
This unit switches the neutral (1P+N), so it disconnects both line and neutral on overcurrent or manual isolation — useful for installations requiring full pole isolation. Rated for ambient -25 to +45 °C, with periodic excursions to +55 °C at up to 95% humidity. Mechanical life is 10 000 switching cycles typical. IP20 with conductors connected; overvoltage category 3. Halogen-free and silicon-free construction.
