5SU1656-0KK10 SIEMENS

The 5SU1656-0KK10 from Siemens is a Residual Current Circuit Breaker with Overcurrent protection (RCBO), designed to provide comprehensive protection against both overload/short circuits and residual currents. This device offers 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 quickly in the event of a ground fault, minimizing the risk of electric shock. It has a B characteristic, which means it trips at currents between 3 and 5 times the rated current, 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 unit, saving space in the distribution board and simplifying installation. It is ideal for protecting circuits with sensitive electronic equipment or where increased safety is required.
