5SU1356-1KK08 SIEMENS

The 5SU1356-1KK08 is a Residual Current Circuit Breaker with Overcurrent protection (RCBO) from Siemens, designed to provide comprehensive protection against both overcurrents and residual currents. This RCBO has a breaking capacity of 6 kA, 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 30 mA, it quickly responds to leakage currents, minimizing the risk of electric shock. It has a C-Characteristic tripping curve, suitable for applications with moderate inrush currents. The rated current (In) is 8 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 compact unit, saving space in electrical panels and simplifying installation. It is ideal for residential, commercial, and industrial applications where both overcurrent and residual current protection are required to ensure safety and prevent electrical hazards.
