5SU1353-1KK16 SIEMENS

The 5SU1353-1KK16 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 4.5 kA, suitable for standard residential and commercial applications. It features a 1P+N (one pole plus neutral) configuration, ensuring both live and neutral conductors are protected. The Type AC designation indicates its ability to detect AC residual currents. With a sensitivity of 30 mA, it quickly trips in the event of a ground fault, minimizing the risk of electric shock. The C-characteristic tripping curve makes it suitable for circuits with moderate inrush currents, such as lighting and general-purpose outlets. It has a rated current (In) of 16 A and a rated voltage (Un) of 230 V AC. This RCBO combines the functionality of a Miniature Circuit Breaker (MCB) and a Residual Current Device (RCD) in a single compact unit, saving space in the distribution board and simplifying installation. It is designed to protect people and equipment from electrical hazards.
