The Type A RCD element (30 mA sensitivity) detects sinusoidal AC residual currents plus pulsating DC residual currents up to 6 mA smooth DC superimposed — the standard choice for circuits with single-phase rectified loads like washing machines, LED drivers, or small VFDs. The C-curve (40 A In) means the magnetic trip fires at 5 to 10 times rated current (200–400 A), so it holds through motor inrush and capacitive loads without nuisance tripping.","metaTitle":"Siemens 5SU9346-7CR40 RCBO, 6 kA, Type A, 30 mA, C-40 A","metaDescription":"Siemens 5SU9346-7CR40 RCBO, 1P+N, 6 kA breaking capacity, Type A RCD, 30 mA, C-curve, 40 A, 230 V AC.
