Weidmueller VPU I 0 N-PE 260V/100KA

The VPU I 0 N-PE 260V/100KA is a voltage protection unit for AC systems. "I" likely refers to a specific protection class or type. "0" indicates protection for a single circuit or configuration, potentially without a neutral connection. "N-PE" refers to protection between the neutral (N) and protective earth (PE), ensuring that any potential surges or faults between these two points are mitigated. "260V" represents the voltage rating, and "100KA" signifies the surge current rating, meaning the unit can handle up to 100 kA of surge current. This unit provides high-level surge protection, especially in systems where neutral-to-earth fault or surge protection is critical, and is typically used in industrial or commercial applications requiring robust surge protection.
