5SU9304-1KK20 SIEMENS

The 5SU9304-1KK20 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 has 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 device is a Type AC RCBO, which detects sinusoidal alternating residual currents. With a sensitivity of 30 mA, it quickly trips in the event of a ground fault, minimizing the risk of electric shock. It has a C-Characteristic tripping curve, which is suitable for circuits with moderate inrush currents, such as lighting and general-purpose circuits. The rated current (In) is 20 A, and the rated voltage (Un) is 230 V AC. This RCBO comes with a pigtail of 600 mm length, facilitating easy connection to the neutral conductor. The solid neutral ensures a reliable and consistent neutral connection.
