Weidmueller VPU AC I BS60 3 R 300/12.5 LCF

The VPU AC I BS60 3 R 300/12.5 LCF is a voltage protection unit for AC systems. "AC" refers to alternating current, "I" indicates the protection type, and "BS60" may represent a specific model or series. "3" denotes three-phase protection, "R" likely refers to a reset function, "300" is the voltage rating, "12.5" is the surge current rating, and "LCF" indicates a feature such as Low Current Failure. The unit can handle surge currents up to 12.5kA, providing robust protection against voltage surges and fluctuations.
