Product Description

Rmu Accessories 12kv Indoor Sf6 Gas Vcb 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 prevention
