Weidmueller VPU AC I 3 R 440/25 LCF

The VPU AC I 3 R 440/25 LCF is a voltage protection unit for AC systems, offering three-phase protection ("3"). "R" indicates the presence of a reset function, allowing the unit to restore normal operation after a fault. "440" refers to the voltage capacity, and "25" denotes the current rating or another key operational parameter. "LCF" likely stands for low-frequency protection or load current filtering, helping to stabilize voltage and prevent fluctuations. This unit is designed to protect electrical equipment from voltage surges and fluctuations, commonly used in industrial and commercial settings for enhanced protection and system reliability.
