Weidmueller VPU AC I 3+1 275/25 LCF S 2PE

The VPU AC I 3+1 275/25 LCF S 2PE is a voltage protection unit for AC systems, providing three-phase plus neutral protection ("3+1"). "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. "S" suggests surge protection, and "2PE" may indicate a two-pole earth connection or specific wiring configuration for grounding. This unit is designed to protect electrical equipment from voltage surges and fluctuations, commonly used in industrial and commercial environments to ensure system reliability and safety.
