Weidmueller VPU I 0 LCF 280V/12,5KA

The VPU I 0 LCF 280V/12.5KA is a voltage protection unit for AC systems. "I" refers to a specific protection class or type. "0" likely indicates protection for a single circuit or configuration, potentially without a neutral connection. "LCF" could denote a feature such as "Low Current Failure" or another specialized protective mechanism. "280V" represents the voltage rating, and "12.5KA" signifies the surge current rating, meaning the unit can withstand up to 12.5 kA of surge current. This unit is designed to protect electrical equipment from voltage surges and fluctuations, typically used in industrial or commercial systems requiring moderate surge current handling along with additional features like the LCF protection.
