5SU1354-1KK16 SIEMENS

The 5SU1354-1KK16 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 interruption of high fault currents to prevent damage to electrical installations. It features a 1P+N configuration, meaning it protects one phase and the neutral conductor, making it suitable for single-phase applications. The device is a Type AC RCBO, which detects sinusoidal alternating 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 16 A, suitable for protecting circuits with a maximum load of 16 amperes. The rated voltage (Un) is 230 V AC, which is standard for residential and commercial power supplies. 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.
