The equipment specifications:
• Interchangeable with ADVAC
• Completely concealed moving parts
• UL Labeling and CSA compliance
• Low Power consumption
• ANSI compliance at 5, 15, and 27 kV
The AMVAC is the first
vacuum circuit breaker
to combine low
maintenance embedded
vacuum interrupters, a
low maintenance
magnetic actuator, and a
maintenance-free
electronic controller.
The result is a medium
voltage circuit breaker
capable of 100,000
operations.
