The integrated residual current element detects AC fault currents at 30 mA, providing personal protection against direct contact. The higher IEC figure applies when the device is installed per the manufacturer's instructions — typically in an industrial distribution board with an upstream backup fuse or MCCB. The energy limiting class of 3 keeps let-through energy low enough to protect downstream wiring. Above that, derate linearly: 59.22 A at 40 °C, 57.33 A at 45 °C, 54.81 A at 50 °C, and 51.03 A at 55 °C.","metaTitle":"Siemens 5SU9356-1KN63 SENTRON RCBO, 63 A, 30 mA, C Curve","metaDescription":"Siemens 5SU9356-1KN63 SENTRON RCBO, 2-pole 1P+N, 63 A rated at 30 °C, 30 mA AC fault current, C tripping characteristic, 6 kA (EN 60898) / 10 kA (IEC 60947-2).
