5SM2322-0 SIEMENS

The 5SM2322-0 is a residual current (RC) unit manufactured by Siemens, designed for use with 5SY series miniature circuit breakers (MCBs). This 2-pole RC unit provides enhanced protection against electrical hazards by detecting residual currents. It is specifically designed for AC type faults, ensuring reliable tripping in the presence of alternating current leakage. The unit has a rated current (In) of 40A, indicating the maximum current it can continuously carry without tripping. Its sensitivity is rated at 30mA, meaning it will trip when a leakage current of 30 milliamperes or greater is detected. The rated voltage (Un AC) is 230V, making it suitable for standard residential and commercial power systems. This RC unit promptly interrupts the circuit upon detecting a fault current, minimizing the risk of electric shock and fire. It is essential for ensuring safety in electrical installations by providing supplementary protection against indirect contact hazards. The 5SM2322-0 RC unit enhances the overall safety and reliability of electrical systems.
