5SU1654-1KK20 SIEMENS

The 5SU1654-1KK20 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 10 kA, ensuring reliable interruption of high fault currents to prevent damage to electrical installations. 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 classified as Type AC, indicating its ability to detect and respond to alternating current residual currents. With a sensitivity of 300 mA, it trips when the leakage current exceeds this threshold, minimizing the risk of electrical shock and fire hazards. The C-Characteristic tripping curve signifies that it is designed for circuits with moderate inrush currents, such as lighting and general-purpose circuits. It has a rated current (In) of 20 A, specifying the maximum continuous current it can carry without tripping under normal operating conditions. The rated voltage (Un) is 230 V AC, making it compatible with standard European and other regions' power grids. This RCBO combines the functionalities of a circuit breaker and a residual current device, offering space-saving and cost-effective protection for residential, commercial, and industrial applications.
