5SU1353-7KK16 SIEMENS

The 5SU1353-7KK16 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 4.5 kA, making it suitable for residential and commercial applications where moderate fault currents are expected. It features a 1P+N configuration, meaning it protects one phase and the neutral conductor, ensuring complete circuit isolation in case of a fault. The device is a type A RCBO, which is sensitive to both AC and pulsating DC residual currents, offering enhanced protection against a wider range of fault conditions. With a residual current tripping sensitivity of 30 mA, it quickly disconnects the circuit in the event of a ground fault, minimizing the risk of electric shock. The C-characteristic tripping curve indicates that it is designed for circuits with moderate inrush currents, such as lighting and general-purpose circuits. It has a rated current (In) of 16 A, suitable for protecting circuits with a maximum load of 16 amperes. The rated voltage (Un) is 230 V AC, which is the standard voltage for residential and commercial power distribution in many countries. 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. Siemens RCBOs are known for their reliability and compliance with international standards, ensuring safe and dependable operation.
