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 — a 15 % drop from the 30 °C figure. ## Residual current type and design The residual-current element is Type AC — it detects sinusoidal AC earth-fault currents only. The design is instantaneous (no intentional time delay), so it trips within the standard RCD response time on a 30 mA fault. This is suitable for general socket-outlet protection but not for selectivity with upstream delayed RCDs.","metaTitle":"Siemens 5SU9356-1CN63 SENTRON RCBO, 63A C-Curve 30mA 6kA","metaDescription":"Siemens 5SU9356-1CN63 SENTRON RCBO, 63A rated, C-curve, 30mA residual current, 6kA breaking capacity per EN 60898 & IEC 60947-2.
