The C-curve and 30 mA sensitivity make it a common choice for final circuits supplying socket outlets, lighting, or small appliances where both overcurrent and shock protection are required in one DIN-rail unit. The IP20 rating applies once installed in a distribution board with conductors connected — handle and store with the board closed. ## Thermal derating — what the ratings mean in a panel At 40 °C the continuous current must be derated to 15.04 A, at 45 °C to 14.56 A, at 50 °C to 13.92 A, and at 55 °C to 12.96 A. ## Compliance and approvals Designed to EN 60898 (breaking capacity 6 kA), pollution degree 2, overvoltage category III, surge voltage resistance 4 000 V. Halogen-free and silicon-free construction. Functional marking per EN 61346-2 and IEC 81346-2: letter F.","metaTitle":"Siemens SENTRON 5SU9356-1KN16 RCBO, 16 A, 30 mA, Type AC, C-","metaDescription":"Siemens SENTRON 5SU9356-1KN16 RCBO, 16 A rated, 30 mA residual current, Type AC, C-curve, 6 kA breaking capacity.
