5SU1323-1BB06 SIEMENS

The 5SU1323-1BB06 is a 2-pole Residual Current Circuit Breaker with Overcurrent protection (RCBO) from Siemens, designed for residential and similar applications. This RCBO combines the functionality of a residual current device (RCD) and a miniature circuit breaker (MCB) in a single compact unit. It provides protection against short circuits, overloads, and residual currents, ensuring the safety of electrical circuits and preventing electrical shocks. The device has a breaking capacity of 4.5 kA, indicating its ability to safely interrupt fault currents up to this level. It is a Type AC RCBO, meaning it is designed to detect AC residual currents. The sensitivity of 30 mA ensures rapid disconnection in case of earth leakage faults, minimizing the risk of electric shock. It features a C-characteristic tripping curve, suitable for circuits with moderate inrush currents. The rated current (In) is 6A, and the rated voltage (Un) is 400V AC, making it suitable for standard residential power supplies.
