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.","metaTitle":"Siemens SENTRON 5SU1344-1RC32 RCBO, 32A, 4P, C-Curve, 30mA,","metaDescription":"Siemens SENTRON 5SU1344-1RC32 RCBO, 32 A rated, 4-pole, C characteristic, 30 mA residual current, 10 kA (EN 60898) / 15 kA (IEC 60947-2).
