Weidmueller VPU AC I 3 440/25 LCF

The VPU AC I 3 440/25 LCF is a voltage protection unit for AC systems, offering three-phase protection ("3"). "440" refers to the voltage capacity, and "25" indicates the current rating or another key operational parameter. "LCF" likely stands for low-frequency protection or load current filtering, which helps reduce voltage fluctuations and ensures stable operation. This unit is designed to protect electrical equipment from voltage surges and fluctuations, making it suitable for industrial and commercial applications where reliable protection of electrical systems is needed.
