The C-curve tripping characteristic means it handles inrush from motor or transformer loads up to 10× rated current before the magnetic trip fires, so it's a common choice for general-purpose distribution circuits feeding mixed inductive and resistive loads. Breaking capacity is 6 kA per both EN 60898 and IEC 60947-2, adequate for most residential and light commercial panelboards where the prospective fault current stays under that threshold. Occupies 7 modular width units on a DIN rail — 126 mm wide, 77 mm deep, 90 mm tall. Installation depth is 70 mm. ## Thermal derating and environment Derate to 58.6 A at 40 °C, 56.1 A at 45 °C, 54.8 A at 50 °C, and 53.6 A at 55 °C. If your panel runs warm, size the upstream protection accordingly.","metaTitle":"Siemens 5SU9346-1CN63 SENTRON RCBO, 63 A, 30 mA, Type AC, C-","metaDescription":"Siemens 5SU9346-1CN63 SENTRON RCBO, 63 A rated, 30 mA residual current, Type AC, C-curve, 6 kA breaking capacity.
