It breaks faults at 4.5 kA per EN 60898 and 15 kA per IEC 60947-2, giving you two ratings to match the applicable standard for the panel design. The 30 mA sensitivity covers personnel protection against line-to-ground faults on AC circuits, while the C curve handles moderate inrush from motorized or fluorescent loads without nuisance tripping.
Solid or stranded conductors from 0.75 to 35 mm² are accepted under the screw terminals; tighten to 2.5–3 N·m.
Mechanical endurance is 10 000 switching cycles typical. Surge current withstand is 1 kA (8/20 μs waveform). Overvoltage category III, energy limiting class 3. Halogen-free and silicon-free construction. Touch protection is built in.
