5SU1354-7KK32 SIEMENS

The 5SU1354-7KK32 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 it can handle substantial fault currents without compromising safety. 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 A RCBO, which is sensitive to both AC and pulsating DC residual currents, offering enhanced protection against a wider range of fault types. 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 32 A, suitable for circuits with a moderate load demand. The rated voltage (Un) is 230 V AC, which is standard for many residential and commercial power systems. 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 adherence to stringent safety standards, making them a trusted choice for electrical protection.
