5SU1356-1KK32 SIEMENS

The 5SU1356-1KK32 is a Residual Current Circuit Breaker with Overcurrent protection (RCBO) from Siemens, designed to safeguard electrical circuits from both overload/short circuits and residual current faults. This RCBO has a breaking capacity of 6kA, indicating its ability to safely interrupt fault currents up to 6000 Amperes. It features a 1P+N configuration, meaning it protects one phase and the neutral conductor. The device is a Type AC RCBO, making it suitable for detecting AC residual currents. With a sensitivity of 30mA, it quickly trips upon detecting even small leakage currents, preventing electrical shocks. It has a C-Characteristic tripping curve, providing a balance between sensitivity and resistance to nuisance tripping. The rated current (In) is 32A, specifying the maximum current the device can continuously carry without tripping under normal conditions. It is designed for a rated voltage (Un) of 230V AC. This RCBO combines the functionality of a Miniature Circuit Breaker (MCB) and a Residual Current Device (RCD) in a single compact unit.
