High power resistors HPR / VHPR

Construction and execution

Our high power resistors consist of a resistor element with a resistor winding made of a special wire, housed in an aluminium case. High power resistors have a high load capacity and offer a high electric strength. All types of the series VHPR feature an increased impulse solidity. Their compact form as well as the design of their connection elements facilitate the installation of the resistor elements and make it user friendly. The overall protective cover prevents dirt particles from entering and provides additional safety in case of an incidental body contact.

  • Protection degree at least IP50, available up to IP65 (depending on type)
  • On request with thermo-contact or PTC sensor
  • UL listed available

Application fields

  • Braking resistors for drives with frequency converters
  • Snubber resistors
