The Type AC residual current detection picks up sinusoidal AC earth faults only; if the load has VFDs, switched-mode supplies, or rectifiers that generate pulsed DC fault currents, you need a Type A or F device instead. The 16 A rating is at 30 °C ambient; at 40 °C it derates to 15.2 A, at 50 °C to 14.4 A, and at 70 °C to 12.32 A. The IP20 rating assumes the distribution board is installed with connected conductors; it's not a standalone outdoor device.","metaTitle":"Siemens 5SU1454-1KK16 SENTRON RCBO, 16A C-curve, 10kA","metaDescription":"Siemens 5SU1454-1KK16 SENTRON RCBO, 16 A rated, C characteristic, Type AC residual current, 10 kA (EN 60898) / 20 kA (IEC 60947-2).
