5SU1353-1KK10 SIEMENS

The 5SU1353-1KK10 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 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 detects sinusoidal alternating residual currents. With a sensitivity of 30 mA, it quickly disconnects the circuit upon detecting even small leakage currents, preventing electrical shocks and fire hazards. Its C-Characteristic tripping curve indicates that it is designed to handle moderate inrush currents, making it suitable for circuits with inductive loads. The RCBO is rated for a nominal current of 10 A and an AC voltage of 230 V, commonly used in single-phase power systems. This RCBO combines the functionality of a circuit breaker and a residual current device into a single compact unit, saving space in the distribution board and simplifying installation. It offers reliable protection against overloads, short circuits, and earth faults, ensuring the safety of people and equipment. The Siemens 5SU1353-1KK10 RCBO is a dependable solution for modern electrical installations.
