Surge voltage resistance is 4 000 V, with a surge current withstand of 1 kA at 8/20 μS waveform. ## Thermal derating — what the 63 A rating means in a warm panel At 40 °C it derates to 58.6 A, at 45 °C to 56.1 A, at 50 °C to 54.8 A, and at 55 °C to 53.6 A. In a crowded enclosure with multiple RCBOs side by side, the real continuous current capability may be lower than the label suggests — factor the derating curve into your panel thermal analysis. Dimensions are 72 mm wide (4 modular width units), 90 mm tall, 77 mm deep with a 70 mm installation depth. The IP20 rating applies only when the distribution board is installed and conductors are connected — this is an open-back device, not for standalone use. Halogen-free and silicon-free construction, so it meets material restrictions for clean environments or green-building specs.","metaTitle":"Siemens SENTRON 5SU9326-1CR63 RCBO, 63 A, 30 mA, Type AC, 6","metaDescription":"Siemens SENTRON 5SU9326-1CR63 RCBO, 63 A rated, 30 mA residual current, 6 kA breaking capacity per EN 60898.
