It carries a Type A residual current sensitivity of 30 mA and a C-Characteristic overcurrent trip curve, rated at 32 A on a 230 V AC supply with a breaking capacity of 4.5 kA. The 30 mA Type A residual current rating means it detects sinusoidal AC faults plus pulsating DC fault currents — the standard requirement for circuits feeding electronics, variable-speed drives, or appliances with rectified loads. The C-Characteristic curve (10 to 15 times In magnetic trip) handles inrush from motor starters, lighting ballasts, or small compressors without nuisance tripping. ## Panel integration Snap-on DIN rail mount for standard 35 mm profile. Single-module width saves rail space in a crowded enclosure. The 1P+N configuration switches the line conductor and provides neutral switching on the outgoing side — check that your distribution board's neutral bar arrangement matches this topology.","metaTitle":"Siemens 5SU9353-7CN32 RCBO, 1P+N, Type A, 30mA, C-Char, 32A,","metaDescription":"Siemens 5SU9353-7CN32 RCBO, 1P+N, Type A, 30 mA, C-Characteristic, In: 32 A, Un AC: 230 V, Icn: 4.5 kA.
