It's the go-to for protecting lighting, control transformers, or small resistive loads in a panel where the branch needs a 1 A thermal-magnetic breaker that also serves as a disconnecting means (isolation suitability per EN/IEC 60898-1 and EN/IEC 60947-2).
Rated 50 kA Icu at 240 V AC (EN/IEC 60947-2) and 6 kA Icn at 230 V AC (EN/IEC 60898-1). The 6 kA Icn is the standard domestic/commercial rating; the 50 kA Icu gives you headroom for industrial coordination studies.
Width is 18 mm (2 x 9 mm pitches), height 91 mm, depth 78.5 mm — fits a standard distribution board or sub-panel without surprises. Double terminals top and bottom accept 1–25 mm² rigid or 1–16 mm² flexible, with a 2 N.m torque spec and 14 mm strip length. IP20 finger-safe terminals.
