5SU1654-1KK10 SIEMENS

The 5SU1654-1KK10 is a Residual Current Circuit Breaker with Overcurrent protection (RCBO) from Siemens, designed to provide comprehensive protection against both overload/short circuit and residual current faults. This RCBO offers a breaking capacity of 10 kA, ensuring reliable disconnection in the event of high fault currents. It features a 1P+N configuration, meaning it protects one phase and the neutral conductor, making it suitable for single-phase applications. The device is a Type AC RCBO, which detects sinusoidal alternating residual currents. With a sensitivity of 300 mA, it trips when the residual current exceeds this threshold, preventing electrical shocks and fire hazards. It has a C-characteristic tripping curve, indicating it is designed for circuits with moderate inrush currents, such as lighting and general-purpose circuits. The rated current (In) is 10 A, suitable for protecting circuits with a maximum current draw of 10 amperes. The rated voltage (Un) is 230 V AC, making it compatible with standard European and other regions' single-phase power systems. 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.
