5SM2347-6 SIEMENS

The 5SM2347-6 is a residual current (RC) unit manufactured by Siemens, designed for use with 5SP4 circuit breakers. This RC unit is a 4-pole device, making it suitable for three-phase systems with a neutral conductor. It provides Type A residual current protection, which means it is sensitive to both AC and pulsating DC residual currents. The rated current (In) of this RC unit is 100 A, indicating its capacity to handle high current loads. It has a tripping current (IΔn) of 30 mA, ensuring sensitive protection against earth leakage faults. The rated voltage (Un) is 400 V AC, making it compatible with standard European power grids. This RC unit is crucial for preventing electrical shocks and fire hazards caused by ground faults. It enhances the safety and reliability of electrical installations in residential, commercial, and industrial settings. Its robust design and precise tripping characteristics ensure dependable protection against residual currents.
