5SU1656-6KK16 SIEMENS

The 5SU1656-6KK16 is a Residual Current Circuit Breaker with Overcurrent protection (RCBO) from Siemens, designed to offer comprehensive protection against both short circuits and residual currents. This RCBO has a breaking capacity of 6 kA, making it suitable for standard residential and commercial applications. It features a 1P+N configuration, meaning it protects one phase and the neutral conductor. The device is a type A RCBO, which is sensitive to both AC and pulsating DC residual currents, enhancing its ability to detect a wider range of fault conditions. With a residual current tripping value of 300 mA, it provides a balance between sensitivity and avoidance of nuisance tripping. The RCBO has a B characteristic, indicating its suitability for circuits with moderate inrush currents, such as lighting and general-purpose circuits. It is rated for a nominal current (In) of 16 A and an AC voltage (Un AC) of 230 V. 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 ensures protection against overload, short circuit, and earth leakage faults, enhancing electrical safety. The 5SU1656-6KK16 is compliant with relevant IEC standards, ensuring quality and safety.
