It carries a 40 A rated current at 400 V AC, 50 Hz, with a C tripping characteristic — meaning it holds up to 5–10× rated current for short overloads and trips faster on higher faults, typical for motor and general-purpose branch circuits.
Snap-on DIN-rail mount, 3 width units (approx. 54 mm), installation depth 55 mm. IP20 finger-safe terminals. Overvoltage category 3 and energy limiting class 3 — suitable for fixed-installation distribution boards where the breaker provides both overload and short-circuit protection downstream. The switched neutral (3P+N) means the neutral is disconnected when the breaker is off, which some local wiring codes require for final circuits.
