It carries a 20 A rated current at 30 °C with a C tripping characteristic and a 30 mA residual current sensitivity, breaking capacity rated at 6 kA per EN 60898 and IEC 60947-2. The 20 A rating holds at 30 °C ambient; at 40 °C it derates to 18.6 A, at 45 °C to 17.6 A, at 50 °C to 17.2 A, and at 55 °C to 16.6 A. If the panel runs warm — say a crowded enclosure near a drive cabinet — use the 40 °C figure for continuous load planning. Depth is 77 mm, installation depth 70 mm, width 126 mm, height 90 mm. Mounting position is any — no restriction for horizontal or vertical rail orientation. IP20 with conductors connected, so it lives inside a distribution board, not exposed to washdown. Touch protection is built in.","metaTitle":"Siemens 5SU9346-1CN20 SENTRON RCBO, 4P, 20 A, 30 mA, C-Char","metaDescription":"Siemens 5SU9346-1CN20 SENTRON RCBO, 4-pole, 20 A rated, 30 mA residual, C characteristic, 6 kA breaking capacity.
