Rated 13 A at 30 °C with a C-curve magnetic trip (5–10 × In) and 300 mA earth-leakage sensitivity, it breaks up to 6000 A Icn at 230 V AC per EN/IEC 61009. The Type A-SI (Super Immunised) designation means it resists nuisance tripping from high-frequency leakage currents common on modern electronic loads — switched-mode power supplies, VFDs, LED drivers — that would trip a standard Type A device.
Snaps onto standard DIN rail (mounting support per). Occupies 4 × 9 mm pitches — a single 36 mm width — so it fits a compact outgoer position in a residential or light-commercial distribution board. Embedding depth is 72 mm, leaving clearance behind the gland plate in a standard 100 mm enclosure.
