Weidmueller VPU I 0 N-PE 440V/50KA

The VPU I 0 N-PE 440V/50KA is a voltage protection unit designed for AC systems. "I" refers to a specific protection class or type. "0" indicates protection for a single circuit or configuration, potentially without a neutral connection. "N-PE" stands for protection between the neutral (N) and protective earth (PE), safeguarding against voltage surges or faults between these two points. "440V" represents the voltage rating, and "50KA" signifies the surge current rating, meaning the unit can handle up to 50 kA of surge current. This unit is typically used in industrial or commercial settings where robust protection against large voltage surges and neutral-to-earth faults is necessary.
