Overview
The GE 52A1 vacuum interrupter bottle is a critical switching component designed for GE PowerVac vacuum circuit breakers operating at medium voltages. Manufactured by General Electric, this unit functions as a replaceable cartridge in high-voltage switchgear and panelboard applications requiring reliable arc interruption.
Key Features
- Rated 5kV system voltage with 1200A continuous current handling
- 29kA short-circuit interrupting capacity for fault protection
- Vacuum interrupter design eliminates arc reignition and extends contact life
- Compatible with GE VB and VB1 vacuum circuit breaker frames
- Separable bottle design enables field replacement without major disassembly
- Bellows assembly prevents contact arcing during opening cycles
Technical Specifications
Vacuum interrupters operate by isolating contacts in a sealed, evacuated chamber. When circuit current is interrupted, the vacuum environment prevents arc continuation, enabling reliable high-voltage switching with minimal contact erosion compared to oil or gas-insulated alternatives.
Typical Applications
- GE PowerVac vacuum circuit breaker replacement cartridges
- Medium-voltage industrial switchgear (3–15kV class)
- Panelboard and switchgear retrofit/repair
- Load-break switching in electrical distribution systems
- Maintenance replacements in existing GE installations
