It combines a Type A residual current device (RCD) with 30 mA sensitivity and a C-curve miniature circuit breaker (MCB) characteristic, all in a single module that snaps onto a DIN rail inside a distribution board. The Type A RCD detects sinusoidal AC residual currents plus pulsating DC residuals — the kind you get from single-phase rectifiers in washing machines, LED drivers, or small VFDs. The 30 mA trip threshold meets the standard for personal protection against direct contact (IEC 60364). The C-curve (C-Char) means the overcurrent element trips at 5 to 10 times rated current, sized for motor or lighting inrush without nuisance tripping. The 6 kA short-circuit breaking capacity (Icn) is the standard for domestic and light commercial final circuits in most European installations. It safely interrupts a fault current up to 6 kA at 230 V AC without welding the contacts or damaging the enclosure.","metaTitle":"Siemens 5SU9326-7CN50 RCBO, Type A, 30 mA, 50 A, C-Char","metaDescription":"Siemens 5SU9326-7CN50 RCBO, 1P+N, 6 kA, Type A, 30 mA, C-Char, 50 A, 230 V AC.
