5SU1323-1BB32 SIEMENS

The 5SU1323-1BB32 is a 2-pole Residual Current Circuit Breaker with Overcurrent protection (RCBO) from Siemens, designed for residential and similar applications. This RCBO combines the functionality of a circuit breaker and a residual current device (RCD) in a single unit, providing protection against both overload/short circuit and residual current faults. It has a breaking capacity of 4.5 kA, suitable for standard residential installations. The device is a Type AC RCBO, meaning it is designed to detect AC residual currents. It features a sensitivity of 30 mA, offering effective protection against electric shock. The C-characteristic tripping curve makes it suitable for circuits with moderate inrush currents. The rated current (In) is 32 A, and the rated voltage (Un) is 400 V AC. This RCBO is commonly used to protect final circuits in residential and commercial buildings, ensuring safety and preventing electrical hazards. It helps in preventing damage to equipment and reducing the risk of fire due to electrical faults. The 5SU1323-1BB32 provides a compact and reliable solution for comprehensive circuit protection.
