5SU1654-0KK10 SIEMENS

The 5SU1654-0KK10 is a Residual Current Circuit Breaker with Overcurrent protection (RCBO) from Siemens, designed to provide comprehensive protection against both overload/short circuits and residual currents. This RCBO is a 1P+N device, meaning it has one protected pole and a neutral pole, suitable for single-phase applications. It features a breaking capacity of 10 kA, ensuring it can safely interrupt high fault currents. The device is a Type AC RCBO, which detects sinusoidal alternating residual currents. With a sensitivity of 300 mA, it trips when the leakage current exceeds this value, preventing electrical shocks and fire hazards. It has a B characteristic, indicating its tripping behavior for overcurrent protection, suitable for resistive and inductive loads with low inrush currents. The rated current (In) is 10 A, and the rated voltage (Un) is 230 V AC. This RCBO combines the functions of a circuit breaker and a residual current device in a single compact unit, saving space in electrical panels and simplifying installation.
