It's a 1P+N design (switched phase, switched neutral) with a C-curve trip characteristic rated 16 A at 30 °C, and a 10 kA breaking capacity certified to both EN 60898 and IEC 60947-2. ## Panel fit and derating The 77 mm overall depth includes the front projection. Derating is significant above 30 °C: 15.04 A at 40 °C, 14.56 A at 45 °C, 13.92 A at 50 °C, and 12.96 A at 55 °C. ## Compliance and environment IP20 with the distribution board installed and conductors connected. Surge current resistance at 8/20 μs is 1 kA. Energy limitation class 3.","metaTitle":"Siemens 5SU9104-1KK16 SENTRON RCBO, 16A C-curve, 10kA, 1P+N","metaDescription":"Siemens SENTRON 5SU9104-1KK16 RCBO, 16A rated at 30°C, C-curve, 10kA breaking capacity per EN 60898. 1P+N, 18mm wide.
