5SU1656-1KK40 SIEMENS

The 5SU1656-1KK40 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 6 kA, ensuring reliable interruption of fault currents to prevent damage to electrical systems and equipment. It features a 1P+N configuration, meaning it protects one phase and the neutral conductor, making it suitable for single-phase applications. The device is Type AC, indicating its ability to detect and respond to alternating current residual currents. With a sensitivity of 300 mA, it trips when leakage currents exceed this threshold, minimizing the risk of electrical shock. The C-Characteristic tripping curve signifies its suitability for circuits with moderate inrush currents, such as lighting and general-purpose circuits. Rated for a current of 40 A, this RCBO is designed for circuits with a maximum current demand of 40 amperes. It operates at a rated voltage of 230 V AC, which is standard for many residential and commercial power systems. This RCBO combines the functions of a circuit breaker and a residual current device in a single compact unit, saving space in electrical panels and simplifying installation. The 5SU1656-1KK40 provides enhanced safety and protection for electrical installations and users.
