5SU1656-6KK25 SIEMENS

The 5SU1656-6KK25 is a Residual Current Circuit Breaker with Overcurrent protection (RCBO) from Siemens, designed for reliable protection against both short circuits and residual currents. This device offers a breaking capacity of 6 kA, ensuring effective interruption of fault currents in residential and commercial applications. It features a 1P+N configuration, meaning it protects one phase and the neutral conductor, making it suitable for single-phase electrical systems. The RCBO is a type A device, which means it is sensitive to both AC and pulsating DC residual currents, providing enhanced safety. With a residual current tripping sensitivity of 300 mA, it offers a balance between protection against electric shock and nuisance tripping. The B characteristic tripping curve indicates that it is designed for applications with moderate inrush currents, such as lighting and general-purpose circuits. It has a rated current (In) of 25 A and is designed for a rated AC voltage (Un AC) of 230 V. This RCBO combines the functions of a circuit breaker and a residual current device in a single compact unit, saving space in the distribution board and simplifying installation. It is suitable for use in a variety of applications, including residential, commercial, and industrial settings, where protection against both overcurrents and residual currents is required.
