It occupies 7 modular width units (126 mm) on the DIN rail and is designed for 50 Hz AC systems at 415 V rated voltage.
That 15 kA figure under the industrial standard means this unit can interrupt higher prospective fault currents than its domestic rating suggests — useful for sub-distribution boards fed by a transformer with low impedance. The C characteristic (5–10× In magnetic trip) handles motor inrush and transformer energization without nuisance tripping on moderate starts.
The 70 mm installation depth matches standard SENTRON distribution board cutouts. IP20 with conductors connected — intended for enclosed distribution boards where the front panel provides the environmental seal.
