The AVR is a three insulator, vertical break outdoor air disconnect switch constructed primarily of aluminum. Operation is accomplished by rotation of the rear insulator. Unique construction methods proven through years of field experience, coupled with simple design concepts provide ease of operation.

  • Operation Minimizes Phase Spacing
  • Welded Lamination Design
  • Reverse Loop Contacts For Short Circuit Withstand
  • Great For Interrupting Duty Applications

Product Details


  • The AVR is commonly used in three-phase line or substation applications such as transformer or line disconnecting, breaker isolating, bypassing or bus sectionalizing.
  • Operation of the AVR may be accomplished by either manual control or by motor operator.
