Solid Sealed Indoor High Voltage Vacuum Circuit Breaker
The VS1 type Solid sealed indoor high voltage vacuum circuit breaker adopts solid insulation structure, and uses advanced epoxy sealing technology to organically combine vacuum interrupter, main circuit and insulation support into an integrated solid sealing pole. This design fundamentally solves the environmental tolerance problem of vacuum circuit breaker and makes it more widely used.
Model: VS1
Brand：KEXR
Model: VS1
Brand：KEXR
● Technical characteristics
The VS1 type solid sealed indoor high voltage vacuum circuit breaker adopts long-life vacuum interrupter and epoxy casting solid sealing technology to ensure the long-term stable operation of the circuit breaker. At the same time, the electronic control part of VS1 type solid sealed indoor high voltage vacuum circuit breaker adopts fully electronic design and intelligent control unit, which provides higher maintenance-free and reliability
● Using conditions of the VS1 type solid sealed indoor high voltage vacuum circuit breaker
▶Ambient temperature range: The temperature surround VS1 type solid sealed indoor high voltage vacuum circuit breaker should be -15~40℃(Storage and transportation at -30℃ is allowed )
▶Altitude: The VS1 type solid sealed indoor high voltage vacuum circuit breaker
should be installed less than 1000 meters.
