Weidmueller VPU II 1 R 1000V/40KA AC

The VPU II 1 1000V/40KA AC is a voltage protection unit designed for AC systems. "II" indicates two-phase protection, offering coverage for two phases of the electrical system. "1" likely refers to a specific configuration or level of protection. "1000V" represents the voltage capacity, indicating that this unit can handle up to 1000 volts. "40KA" denotes the surge current rating, which indicates that the unit can protect against surges up to 40,000 amperes. "AC" indicates that the unit is designed for alternating current systems. This unit is used to protect electrical equipment from high-voltage surges and transient faults, making it suitable for industrial and commercial applications where high levels of surge protection are required.
