Product Introduction

 

VS1-Series embedded pole. vacuum circuit breakers are applicable to 12kV, three-phase AC 50Hz indoor switchgear and can serve as protection and control units for industrial and mining establishment transformer substation equipment. With modular and independent-frame design for their spring operating mechanisms, VS1-Series circuit breakers can operate with KYN28 mid-set and fixed switchgear. These circuit breakers are subject to both fixed installation and assembly with truck as a handcart unit

 

Normal service condition

Altitude ≤1000m
Ambient temperature Max +40℃
Min -15℃

Ambient humidity:

Maximum average humidity

24 hours ≤95%
1 month ≤90%
Maximum water vapor pressure 24 hours ≤2.2kpa
1 month ≤1.8kpa

Solar radiation is negligible. Vibration from the outside of switchgears and control-gears is negligible. The ambient air has no obvious pollution of dust smoke, corrosive or combustible gases, steams or smog
