5SU1354-1KK40 SIEMENS

The 5SU1354-1KK40 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 offers 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 leakage currents, minimizing the risk of electric shock. The C-characteristic tripping curve indicates its suitability for circuits with moderate inrush currents. Rated for a current of 40 A and an AC voltage of 230 V, this RCBO is ideal for residential and commercial applications. It combines the functionality of a circuit breaker and a residual current device in a single compact unit, saving space in electrical panels and simplifying installation. This device enhances electrical safety by preventing both overcurrents and earth leakage faults.
