5SU1454-1KK20 SIEMENS

The 5SU1454-1KK20 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 offers a breaking capacity of 10 kA, ensuring reliable interruption of high fault currents to prevent damage to equipment and wiring. It features a 1P+N configuration, meaning it protects one phase and the neutral conductor, making it suitable for single-phase applications. The Type AC designation indicates its sensitivity to alternating current residual currents. With a residual current tripping sensitivity of 100 mA, it provides a balance between protection against earth leakage faults and minimizing nuisance tripping. The C-Characteristic tripping curve signifies its suitability for circuits with moderate inrush currents, such as lighting and general-purpose circuits. Its rated current (In) is 20 A, designed for circuits with a maximum continuous current of 20 Amperes. 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 is ideal for use in residential, commercial, and industrial applications where both overcurrent and residual current protection are required.
