Characteristics:

LS vacuum contactors provide versatile auxiliary functions with high strength and switching capacity. We have high and sustainable technology that no one can reach in this regard.

We provide high performance, high reliability and long service life.

Superior mechanical strength and degassing.

Thanks to the use of high alumina ceramic tube and high temperature degassing, it provides a long service life and is suitable for frequent use.
Short arc time.

Vacuum insulation has a fast recovery feature.

Ability to break the current at the first available zero point when opening, to minimize contact wear.

Reliable failure interruption

The LS current limiting power fuse can protect devices and systems from fault current by breaking them in half a cycle.

Security:

LS vacuum contactors provide various auxiliary functions for safe and convenient use.
