The 18 mm width (1 modular unit) and DIN-rail fastening let it slot directly into a standard distribution board — no extra adapters needed.
The 1P+N configuration switches the line conductor and disconnects the neutral, which is required in many regional wiring rules for single-phase final circuits. Rated insulation voltage (Ui) is 250 V AC, and the overvoltage category is III — suitable for fixed installations downstream of the utility meter. Pollution degree 2 covers normal non-conductive contamination that may become temporarily conductive due to condensation, typical for enclosed distribution boards. Storage range is -40 to +75 °C. The breaker is sealable for anti-tamper applications.
The breaker occupies 1 modular width unit (18 mm).
