Weidmueller VPU AC I F 3+1 R 275/25

The VPU AC I F 3+1 R 275/25 is a voltage protection unit for AC systems, providing three-phase plus neutral protection ("3+1"). "F" could indicate a feature related to frequency or filtering. "R" suggests a reset function, allowing the unit to return to normal operation after a fault. "275" refers to the voltage capacity, and "25" denotes the current rating or another key operational parameter. This unit is designed to protect electrical equipment from voltage surges and fluctuations, commonly used in industrial and commercial applications for reliable system protection.
