It protects a single pole plus neutral in a 1P+N configuration, with a thermal-magnetic trip unit that handles both overloads and short circuits. Breaking capacity: 6 kA Icn at 230 V AC (per EN/IEC 60898-1) and 10 kA Icu at 230–240 V AC (per IEC 60947-2). That dual rating means it's certified for both residential-distribution and industrial-panel use — the higher Icu figure gives headroom for fault-current coordination upstream.
Clip-on mount to standard 35 mm DIN rail. Width is 18 mm (2 x 9 mm pitches), height 81 mm, depth 78 mm — fits a standard distribution board or sub-panel. Neutral is on the left. IP20 rated (finger-safe terminals).
