5SU1353-1KK40 SIEMENS

The 5SU1353-1KK40 is a Residual Current Circuit Breaker with Overcurrent protection (RCBO) from Siemens, designed to safeguard electrical circuits and prevent electrical accidents. This RCBO offers reliable protection against short circuits, overloads, and residual currents, ensuring the safety of both equipment and personnel. With a breaking capacity of 4.5 kA, it can effectively interrupt fault currents in residential and commercial applications. It features a 1P+N configuration, meaning it protects one phase and the neutral conductor. The Type AC designation indicates its suitability for detecting AC residual currents. A 30 mA tripping current provides sensitive protection against earth leakage faults, minimizing the risk of electric shock. The C-Characteristic tripping curve makes it suitable for circuits with moderate inrush currents. Rated for a current of 40 A and a voltage of 230 V AC, this RCBO is ideal for a wide range of applications.
