5SU1354-7KK40 SIEMENS

The 5SU1354-7KK40 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 disconnection in the event of high fault currents. It features a 1P+N configuration, meaning it protects one phase and the neutral conductor. The device is a type A RCBO, which is sensitive to both AC and pulsating DC residual currents. With a residual current tripping sensitivity of 30 mA, it offers enhanced protection against electric shock. It has a C-characteristic tripping curve, suitable for circuits with moderate inrush currents. The rated current (In) is 40 A, making it suitable for circuits with a continuous current demand of up to 40 Amperes. The rated voltage (Un) is 230 V AC, which is the standard voltage for residential and commercial applications. This RCBO combines the functions of a circuit breaker and a residual current device in a single compact unit. It is designed for DIN rail mounting, making it easy to install in standard distribution boards.
