5SU1354-1KK32 SIEMENS

The 5SU1354-1KK32 is a Residual Current Circuit Breaker with Overcurrent protection (RCBO) from Siemens, designed to provide comprehensive protection against both short circuits and residual currents. This RCBO has a breaking capacity of 10 kA, ensuring reliable disconnection in the event of a high fault current. 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 earth leakage faults, minimizing the risk of electric shock. The C-characteristic tripping curve indicates that it is designed for circuits with moderate inrush currents, such as lighting and general-purpose circuits. It has a rated current (In) of 32 A, suitable for circuits with a moderate load demand. The rated voltage (Un) is 230 V AC, which is standard for single-phase applications. 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 is ideal for residential, commercial, and industrial applications where both overcurrent and residual current protection are required.
