Weidmueller VPU AC I 3 R 275/25 LCF S

The VPU AC I 3 R 275/25 LCF S is a voltage protection unit for AC systems, designed for three-phase protection ("3"). "R" indicates a reset function, "275" 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, and "S" suggests surge protection. This unit is designed to protect electrical equipment from voltage surges and fluctuations, commonly used in industrial and commercial settings to ensure the safety and reliability of electrical systems.
