Weidmueller VPU AC I 1+1 R 275/25 LCF S

The VPU AC I 1+1 R 275/25 LCF S is a voltage protection unit for AC systems with dual protection stages ("1+1") for added security. "R" indicates a reset function, "275" 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, and "S" suggests surge protection. This unit is designed to protect electrical equipment from voltage surges and fluctuations, providing enhanced reliability and safety for industrial and commercial applications.
