Power/Vac® Vacuum Breakers
The heart of the GE PowerVac® circuit breaker is the vacuum interrupter. GE pioneered this interrupter technology beginning with experimental work in the 1920's. Today, the vacuum design remains superior to other arc interruption technologies by providing a smaller footprint and simpler design.
Features and Benefits
- Modular design with interchangeable footprint and parts for all breaker sizes
- Comprehensive mechanical and electrical interlocks for operating safety
- Virtually maintenance-free vacuum interrupter contacts
- Direct reading erosion indicator for vacuum interrupter contacts
