5SU1354-0KK06 SIEMENS

The 5SU1354-0KK06 from Siemens is a Residual Current Circuit Breaker with Overcurrent protection (RCBO), designed to provide comprehensive protection against both short circuits and earth leakage faults. This RCBO offers a breaking capacity of 10kA, ensuring reliable interruption of high fault currents to prevent damage to electrical installations. It features a 1P+N (one pole plus neutral) configuration, suitable for single-phase systems with a neutral conductor. The device is a Type AC RCBO, which is sensitive to alternating current residual currents. With a tripping current of 30mA, it quickly disconnects the circuit upon detecting even small leakage currents, minimizing the risk of electric shock. Its B characteristic tripping curve indicates that it is designed for applications with moderate inrush currents, such as lighting and general-purpose circuits. The RCBO has a rated current (In) of 6A and is designed for a rated voltage (Un) of 230V AC, making it suitable for standard residential and commercial power supplies. This RCBO combines the functionality of a circuit breaker and a residual current device in a single compact unit, saving space in electrical panels and simplifying installation. It provides enhanced safety and protection for electrical circuits and connected equipment.
