In a panel with a higher upstream fault level — say a 10 kA or 16 kA main breaker — you need to verify the back-up protection or current-limiting device to ensure the RCBO is not subjected to a fault it cannot interrupt. The 1P+N form factor (switched phase, solid neutral) fits standard single-phase final circuits in TN or TT earthing systems.","metaTitle":"Siemens 5SU9353-7CN50 RCBO, 50A C-Char, 30mA Type A, 4.5kA","metaDescription":"Siemens 5SU9353-7CN50 RCBO, 1P+N, 50 A C-curve, 30 mA Type A residual current, 4.5 kA breaking capacity at 230 V AC.
