Weidmueller VPU AC I 1+1 R 440/25 LCF

The VPU AC I 1+1 R 440/25 LCF is a voltage protection unit for AC systems, providing dual protection stages ("1+1"), which enhances system redundancy. "R" suggests the presence of a reset function, allowing the unit to restore normal operation after a fault. "440" refers to the voltage capacity, and "25" indicates the current rating or another operational parameter. "LCF" likely stands for low-frequency protection or load current filtering, which helps mitigate voltage fluctuations. This unit is designed to protect electrical equipment from voltage surges and fluctuations, commonly used in industrial and commercial applications to ensure reliable protection and stability of electrical systems.
