Weidmueller VPU AC I 4 255/12.5 LCF MB

The VPU AC I 4 255/12.5 LCF MB is a voltage protection unit for AC systems, likely designed for four-phase protection, possibly including neutral ("4"). "255" refers to the voltage capacity, and "12.5" represents the current rating or another key operational parameter. "LCF" likely stands for low-frequency protection or load current filtering. "MB" could indicate motor protection or a specialized feature for specific applications. This unit is intended to protect electrical equipment from voltage surges and fluctuations, commonly used in industrial and commercial environments to ensure the reliability and safety of systems.
