5SU1656-0KK32 SIEMENS

The 5SU1656-0KK32 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 6kA, making it suitable for residential and commercial applications where moderate fault levels are expected. It is a 1P+N device, meaning it combines one protected phase with a neutral conductor, fitting into a single module width on a DIN rail. The device is Type AC, indicating it is designed to detect AC residual currents. With a sensitivity of 300mA, it trips when leakage current exceeds this value, preventing electric shock and fire hazards. It features a B characteristic, providing moderate inrush current tolerance, suitable for resistive and inductive loads with low to medium starting currents. The RCBO is rated for a nominal current (In) of 32A, and a nominal voltage (Un) of 230V AC. This ensures compatibility with standard European power systems. The 5SU1656-0KK32 offers a compact and reliable solution for enhanced electrical safety.
