LS Tri-MEC Vacuum Contactors

LS Tri-MEC vacuum contactors are mainly used for the switching of motors, transformers, capacitors in AC power lines. They can be installed in multi-stack cubicles.

A vacuum contactor comprises several assemblies such as switching mechanism including vacuum interrupters, magnetic actuator, high strength molded front cover and auxiliary devices. Stable and high operating cycle is executed by the vacuum interrupters made of high alumina ceramic tube which makes it possible to degas in a high temperature with excellent mechanical strength.

Actuating is available either at instantaneous or continuous excitation. Functions for safety in connecting and disconnecting are also provided.
