Weidmueller VPU I 0 280V/25KA

The VPU I 0 280V/25KA 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. "280V" represents the voltage rating, and "25KA" signifies the surge current rating, meaning the unit can handle up to 25 kA of surge current. This unit is designed to protect electrical equipment from voltage surges and fluctuations, offering high surge current handling capability, typically used in industrial or commercial environments where robust protection against large surges is needed.
