5SU1654-7KK16 SIEMENS

The 5SU1654-7KK16 is a Residual Current Circuit Breaker with Overcurrent protection (RCBO) from Siemens, designed to provide comprehensive protection against both overload/short circuit and residual current faults. This RCBO has a breaking capacity of 10 kA, making it suitable for applications where high fault currents are possible. It features a 1P+N configuration, meaning it protects one phase and the neutral conductor. The device is a type A RCBO, which is sensitive to both AC and pulsating DC residual currents. It has a residual current tripping sensitivity of 300 mA, providing a balance between protection and minimizing nuisance tripping. The RCBO has a C-characteristic tripping curve, making it suitable for circuits with moderate inrush currents. Its rated current (In) is 16 A, and it 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 unit, saving space and installation time. It is suitable for use in residential, commercial, and industrial applications to protect people and equipment from electrical hazards.
