5SU1653-1KK32 SIEMENS

The 5SU1653-1KK32 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 offers a breaking capacity of 4.5 kA, making it suitable for residential and commercial applications where moderate fault currents are expected. It features a 1P+N configuration, meaning it protects one phase and the neutral conductor, ensuring complete circuit isolation in case of a fault. The device is a Type AC RCBO, which is sensitive to alternating current residual currents. With a sensitivity of 300 mA, it provides a balance between protection against electrical shocks and nuisance tripping. It has a C-Characteristic tripping curve, suitable for circuits with moderate inrush currents, such as lighting and general-purpose circuits. The RCBO is rated for a nominal current (In) of 32 A and an 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 in the distribution board and simplifying installation. It is designed to protect people and equipment from electrical hazards, ensuring a safe and reliable electrical installation. The 5SU1653-1KK32 RCBO is a reliable and efficient solution for modern electrical protection needs.
