This is the current-production variant, still actively manufactured. 16 A rated current at 230/240 V AC covers most single-phase final circuits — lighting, general-purpose sockets, small appliances. The 1P+N configuration switches the line conductor and disconnects the neutral, which is required in many regional wiring rules for final circuits. ## Where it goes in the panel Depth is 77 mm, installation depth 70 mm — fits standard distribution boards and sub-distribution enclosures. Supply can enter from top or bottom, which simplifies busbar routing in dense panels. IP20 rated once installed with conductors connected, so it belongs inside a distribution board, not in a wet or dusty location.","metaTitle":"Siemens SENTRON 5SU9356-1CR16 RCBO, 16 A, 30 mA, Type AC, C-","metaDescription":"Siemens SENTRON 5SU9356-1CR16 RCBO, 16 A rated current, 30 mA residual current, Type AC, C-curve, 6 kA (EN 60898) / 10 kA (IEC 60947-2).
