Weidmueller VPU AC I 0 300/12.5 LH

The VPU AC I 0 300/12.5 LH is a voltage protection unit for AC systems. "0" likely refers to a specific configuration or setting, possibly indicating a default or no-phase protection. "300" represents the voltage capacity, and "12.5" denotes the current rating or another operational parameter. "LH" likely stands for low-harmonic or low-voltage protection, which helps in filtering out unwanted voltage disturbances and harmonics. This unit is designed to protect electrical equipment from voltage surges, fluctuations, and harmonics, commonly used in industrial or commercial settings to ensure stable and reliable operation.
