5SU1653-1KK16 SIEMENS

The 5SU1653-1KK16 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 has a breaking capacity of 4.5 kA, making it suitable for standard residential and commercial applications. It features a 1P+N configuration, meaning it protects one phase and the neutral conductor. The device is a Type AC RCBO, which detects sinusoidal alternating residual currents. With a sensitivity of 300 mA, it offers a balance between protection against electrical shocks and minimizing nuisance tripping. It has a C-Characteristic tripping curve, suitable for circuits with moderate inrush currents. The rated current (In) is 16 A, and it is designed for 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 ensures safety by quickly disconnecting the circuit in case of overcurrent or residual current faults.
