Weidmueller VPU AC I 3+1 R 300/12.5 LCF

The VPU AC I 3 R 300/12.5 LCF is a voltage protection unit for AC systems, designed for three-phase protection ("3"). "R" suggests a reset function, "300" refers to the voltage capacity, and "12.5" denotes the current rating or another key operational parameter. "LCF" likely indicates low-frequency protection or load current filtering. This unit provides protection against voltage surges or fluctuations, commonly used in industrial and commercial applications to ensure the reliability and safety of electrical equipment.
