5SU1356-7KK20 SIEMENS

The 5SU1356-7KK20 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 has a breaking capacity of 6 kA, making it suitable for standard residential and commercial applications. It features a 1P+N (one pole plus neutral) configuration, ensuring both the phase and neutral conductors are protected. The device is a type A RCBO, which means it is sensitive to both AC and pulsating DC residual currents. With a tripping current of 30 mA, it offers effective protection against electric shock. The C-characteristic tripping curve indicates that it is designed for circuits with moderate inrush currents. It has a rated current (In) of 20 A and a rated voltage (Un) of 230 V AC, making it suitable for standard European power grids. This RCBO combines the functionality of a circuit breaker and a residual current device in a single compact unit.
