Weidmueller VPU AC I 4 440/25 LCF

The VPU AC I 4 440/25 LCF is a voltage protection unit for AC systems, offering four-phase protection, including neutral ("4"). "440" refers to the voltage capacity, and "25" represents the current rating or another key operational parameter. "LCF" likely stands for low-frequency protection or load current filtering, which helps mitigate voltage fluctuations and ensures stable operation. This unit is designed to protect electrical equipment from voltage surges and fluctuations, commonly used in industrial and commercial applications to enhance the reliability and safety of electrical systems.
