It trips on residual fault currents at 300 mA, Type B+, which means it catches smooth DC fault currents plus higher-frequency AC components, not just the 50/60 Hz sine wave a standard AC type would miss. That matters on drives, UPS feeds, or PV inverters where DC fault current can blind a basic RCD. At 40 °C ambient the continuous rating drops to 115.62 A; at 50 °C it's 106.25 A; at 60 °C it's 96.25 A.","metaTitle":"Siemens 5SU1674-7DK82 SENTRON RCBO, 4P, 125 A, 300 mA, Type","metaDescription":"Siemens 5SU1674-7DK82 SENTRON RCBO, 4-pole, 125 A rated, 300 mA residual fault current, Type B+, 10 kA breaking capacity per EN 60898.
