5SU1154-7KK10 SIEMENS

The 5SU1154-7KK10 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 is a 1P+N device, meaning it has one protected pole and a neutral pole, suitable for single-phase applications. It features a breaking capacity of 10 kA, ensuring it can handle high fault currents effectively. The device is a type A RCBO, which means it is sensitive to both AC and pulsating DC residual currents. With a sensitivity of 10 mA, it offers a high level of protection against 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 10 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 unit, saving space in the distribution board and simplifying installation. It is suitable for use in residential, commercial, and industrial applications where both overcurrent and residual current protection are required, enhancing electrical safety and preventing damage to equipment.
