5SU1356-0KK32 SIEMENS

The 5SU1356-0KK32 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 6 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 30 mA, it quickly disconnects the circuit in the event of a ground fault, minimizing the risk of electric shock. The B characteristic tripping curve ensures reliable protection against overloads and short circuits, with a moderate tripping speed suitable for typical household loads. Its rated current (In) is 32 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 compact unit, saving space in the distribution board and simplifying installation. It offers enhanced safety and protection for electrical circuits and connected equipment.
