5SM2347-0 SIEMENS

The 5SM2347-0 is a residual current (RC) unit manufactured by Siemens, designed for use with 5SP4 circuit breakers. This 4-pole RC unit provides enhanced protection against electrical faults. It is specifically designed for AC type applications. The rated current (In) is 100 A, indicating its capacity to handle substantial electrical loads. The sensitivity is 30 mA, ensuring rapid response to even small leakage currents. The rated voltage (Un) is 400 V AC, making it suitable for standard industrial and commercial power systems. This RC unit is crucial for preventing electrical shocks and fire hazards. It works by continuously monitoring the balance of current between the supply and return conductors. Any imbalance exceeding the 30 mA threshold triggers the unit to quickly disconnect the circuit. This ensures the safety of personnel and equipment. The 5SM2347-0 is an essential component for comprehensive electrical protection systems.
