The C-curve (magnetic trip between 5× and 10× In) suits motor-starter circuits, small transformers, or lighting banks with moderate inrush — the 32 A rating handles a 7.3 kW resistive load at 230 V or a 5.5 kW motor with appropriate coordination. The 30 mA residual sensitivity provides supplementary protection against direct contact in final circuits, as required by IEC 60364 for socket-outlet circuits and portable equipment. In industrial panels with higher fault levels, upstream fusing or a higher-rated MCB is needed to keep the RCBO within its rated breaking capacity.","metaTitle":"5SU9346-7CN32 RCBO, 6 kA, 1P+N, Type A, 30 mA, C-Char, 32 A","metaDescription":"Siemens 5SU9346-7CN32 RCBO, 6 kA breaking capacity, 1P+N, Type A, 30 mA residual, C-curve, 32 A, 230 VAC.
