Surge Protection Shields (SHZP-U)

4 товара

Overvoltage protection shields ShZP-U correspond to SPD Class I+II (B+C type) and combine the first and the second protection stages during lightning strikes.

 

Intended for the protection of electrical equipment of buildings and structures against direct lightning strikes into the lightning protection system or into overhead power line, as well as against high-energy switching pulse surges. The product is intended for installation on the input feeder of the protected object.

Key advantages:

  • Remote control using "dry" contact interface Remote control using "dry" contact interface
  • Protection against protection modules short circuit at long-term surges or overvoltage pulses Protection against protection modules short circuit at long-term surges or overvoltage pulses
  • Convenient connection in parallel to the grid with minimal interference in wiring Convenient connection in parallel to the grid with minimal interference in wiring
  • Safe maintenance and repair without disconnecting consumers from the protected grid Safe maintenance and repair without disconnecting consumers from the protected grid
  • Can tolerate high value of lightning pulse discharge current (10/350 μs): 35 kA for each phase Can tolerate high value of lightning pulse discharge current (10/350 μs): 35 kA for each phase
  • Indication of protection modules faults (thermal protection response) Indication of protection modules faults (thermal protection response)
