5SU1154-7KK13 SIEMENS

The 5SU1154-7KK13 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 interruption of high fault currents to prevent damage to equipment and wiring. 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 A RCBO, which is sensitive to both AC and pulsating DC residual currents, offering enhanced protection against a wider range of fault conditions. With a residual current tripping sensitivity of 10 mA, it provides a high level of protection against 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 13 A and a rated voltage (Un) of 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 suitable for use in residential, commercial, and industrial applications where both overcurrent and residual current protection are required.
