5SU1654-0KK32 SIEMENS

The 5SU1654-0KK32 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 has a breaking capacity of 10kA, indicating its ability to safely interrupt high fault currents, preventing damage to equipment and ensuring safety. 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 300mA, it trips when the residual current exceeds this value, minimizing the risk of electrical shock. It has a B characteristic tripping curve, which means it trips at 3 to 5 times the rated current, suitable for resistive and inductive loads with low inrush currents. The rated current (In) is 32A, specifying the maximum continuous current it can carry without tripping. The rated voltage (Un) is 230V AC, making it compatible with standard single-phase power systems. This RCBO combines the functionality of a circuit breaker and a residual current device in a single compact unit, saving space in electrical panels and simplifying installation.
