It breaks fault currents up to 6 kA (Icn) and protects against earth leakage at 30 mA sensitivity, Type A — meaning it detects pulsating DC fault currents as well as sinusoidal AC, which covers modern electronics and variable-speed drives in the downstream load. Rated at 50 A with a C-trip characteristic, it handles motor-starting inrush and moderate transformer loads without nuisance tripping, while still clearing short-circuit faults fast enough to protect the final circuit. The 230 V AC single-phase rating makes it a direct fit for residential and light commercial distribution boards across Europe and markets that follow IEC 60898 / 61009 standards.","metaTitle":"Siemens 5SU9346-7CN50 RCBO, 6 kA, Type A, 30 mA, C-Char, 50","metaDescription":"Siemens 5SU9346-7CN50 RCBO, 6 kA breaking capacity, 1P+N, Type A, 30 mA, C-Characteristic, 50 A rated current, 230 V AC.
