5SU1654-6KK25 SIEMENS

The 5SU1654-6KK25 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 it can handle substantial fault currents, and features a 1P+N configuration, meaning it protects one phase and the neutral conductor. It is a type A RCBO, making it sensitive to both AC and pulsating DC residual currents, enhancing its safety performance. The device has a residual current tripping sensitivity of 300 mA, providing a balance between protection against earth faults and minimizing nuisance tripping. Its B characteristic tripping curve indicates it is suitable for applications with moderate inrush currents, such as lighting and general-purpose circuits. The RCBO has a rated current (In) of 25 A and is designed for a rated AC voltage (Un AC) of 230 V. This RCBO combines the functions of a circuit breaker and a residual current device in a single compact unit. It offers space-saving installation and simplified wiring. It is ideal for residential, commercial, and industrial applications where both overload and residual current protection are required.
