Replacement Vacuum Interrupter Pole Assemblies
Compatible With Power/Vac® Circuit Breakers
Utilizing Encapsulated/Embedded Vacuum Interrupters

Encapsulate - embedded vacuum interrupter assembly retrofit Vacuum Interrupters, Inc. is pleased to announce the development and availability of replacement vacuum interrupter pole assemblies compatible with older Power/Vac® circuit breakers using encapsulated - embedded vacuum interrupters. By embedding the vacuum interrupter in epoxy, the assembly is substantially tougher and better suited to withstand impact, moisture, dust, and other environmental contaminates. ANSI/IEEE C37.09 tested and certified for use on compatible circuit breakers, our hardened, superior assembly will enable the user to upgrade and extend the life of original equipment; and, if combined with proper mechanical maintenance of the breaker, extend the life of that equipment another twenty-plus years. They are available now in selected ratings and others will be available in the near future.
