5SU1656-1KK32 SIEMENS

The 5SU1656-1KK32 is a Residual Current Circuit Breaker with Overcurrent protection (RCBO) from Siemens, designed to provide comprehensive protection against both short circuits and residual currents. This device has a breaking capacity of 6 kA, ensuring reliable interruption of fault currents in residential and commercial applications. It features a 1P+N configuration, meaning it protects one phase and the neutral conductor. The RCBO is Type AC, making it suitable for detecting AC residual currents. With a sensitivity of 300 mA, it trips when leakage current exceeds this threshold, preventing electrical shocks and fire hazards. It has a C-Characteristic tripping curve, which allows for moderate inrush currents without nuisance tripping, ideal for circuits with inductive loads. The rated current (In) is 32 A, suitable for circuits with a maximum continuous current of 32 amperes. The rated voltage (Un) is 230 V AC, designed for standard 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.
