5SU1353-1KK06 SIEMENS

The 5SU1353-1KK06 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 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 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 30 mA, it quickly detects and interrupts leakage currents to prevent electric shock. It has a C-Characteristic tripping curve, suitable for circuits with moderate inrush currents, such as lighting and general-purpose circuits. The rated current (In) is 6A, making it appropriate for circuits with a relatively low current demand. The rated voltage (Un) is 230V AC, which is standard for single-phase applications. This RCBO combines the functionality of a circuit breaker and a residual current device in a single unit, saving space in the distribution board and simplifying installation. It enhances electrical safety by providing reliable protection against a wide range of electrical hazards.
