The 30 mA trip threshold provides additional protection against direct contact (personnel protection per IEC 60364). This RCBO fits a single-pole-plus-neutral DIN-rail slot in a distribution board. It combines overcurrent protection (MCB function) and earth-leakage protection (RCD function) in one device, saving space versus separate units. Common in final circuits supplying socket outlets, lighting, or small appliances where both short-circuit and residual-current protection are required.","metaTitle":"Siemens 5SU9356-7CN20 RCBO, 6 kA, Type A, 30 mA, C-Char, 20","metaDescription":"Siemens 5SU9356-7CN20 RCBO, 6 kA breaking capacity, 1P+N, Type A, 30 mA residual current, C characteristic, 20 A rated current, 230 V AC.
