- SF6 Outdoor VCBSF6 Indoor VCBOutdoor Vacuum Circuit Breaker
-
Product Features
· Light structure, small contact distance (10 mm), quick action, light operation, small volume and light weight.
· The arcing time is short, because the contact is in vacuum, there is basically no arc, and the very small arc can be extinguished in half cycle (0.01 second), so it is called half cycle circuit breaker, and it has nothing to do with the current.
· The dielectric recovery speed of contact gap is fast.
· Long service life.
· Less maintenance and fire preventionTechnical Parameters

Applicable conditions
Altitude: ≤2000m;
Ambient air temperature: -45ºC~+50ºC;
Relative humidity: daily average ≤95%, monthly average ≤90%;
It is not suitable for installations where there are frequent and severe vibrations, water vapor, gas, chemical corrosive deposits, salt spray, dust and dirt, and fire and explosion hazard installations that obviously affect the performance of the mechanism.
The rated SF6 gas pressure is 0.04MPa, and the SF6 gas meets the requirements of GB/T 12022-2014 "Industrial SF6″.Production Scenario
