Weidmueller VPU AC I 1 R 440/25 LCF

The VPU AC I 1 R 440/25 LCF is a voltage protection unit for AC systems, offering single-phase protection ("1"). "R" indicates the presence of a reset function, allowing the unit to return to normal operation after a fault. "440" 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, which helps reduce voltage fluctuations. This unit is designed to protect electrical equipment from voltage surges and fluctuations, commonly used in industrial and commercial settings for reliable protection and safety.
