5SM2333-6 SIEMENS

The 5SM2333-6 is a residual current (RC) unit manufactured by Siemens, designed for use with 5SL4 circuit breakers. This RC unit is a three-pole device, ensuring comprehensive protection across all three phases of a three-phase electrical system. It is classified as a Type A RC unit, indicating its ability to detect both AC and pulsating DC residual currents. The rated current (In) of this unit is 40A, signifying the maximum current it can continuously handle without tripping. Its sensitivity is set at 30mA, meaning it will trip when a residual current of 30 milliamperes or greater is detected, providing a high level of protection against electrical shocks. The rated AC voltage (Un AC) is 400V, making it suitable for standard three-phase power systems. This RC unit is crucial for ensuring safety in electrical installations by quickly disconnecting the power supply in the event of a ground fault or leakage current, preventing potential hazards such as electric shocks and fires. It enhances the overall safety and reliability of electrical systems in residential, commercial, and industrial applications. The 5SM2333-6 RC unit offers a compact and efficient solution for residual current protection.
