It breaks fault currents up to 6 kA per EN 60898 and IEC 60947-2, trips on residual currents of 30 mA (Type AC, meaning it detects sinusoidal AC earth faults), and follows a C tripping characteristic for moderate inrush loads like motor starters and lighting banks. Rated 10 A at 400 V AC, it also includes integrated overvoltage protection set at 280 V, which clamps the line-to-neutral voltage before surge damage reaches downstream equipment. ## Panel fit and environmental range Snaps onto DIN rail, occupies 4 modular width units (72 mm wide), with a depth of 77 mm and an installation depth of 70 mm. Operating temperature spans -40 °C to 75 °C, with max 95% humidity. Halogen-free and silicon-free construction, so it won't outgas corrosive compounds in sealed enclosures or near sensitive contacts.","metaTitle":"Siemens 5SU9326-1CS10 SENTRON RCBO, 6kA, 2P, 30mA, C-10A","metaDescription":"Siemens 5SU9326-1CS10 SENTRON RCBO, 6kA breaking capacity per EN 60898, 2-pole, Type AC, 30mA residual, C-curve, 10A rated, 400V AC, with overvoltage protection 280V.
