Compact Design
As a result of compactly designed vacuum bottles and a unique mechanism, mounting space is significantly reduced.

High Insulation Strength
Can respectively withstand voltage for 1 minute and impulse withstand voltage of 6.5kV, and 15kV.

Easy Inspection and Maintenance
Due to vacuum switches located up front, replacing and checking contacts for wear is made easy without disconnecting cables.

Surge Absorber is not Required
The virtue of the contacts being made of special material that suppresses current chopping to a minimum level; a surge absorber is not required.

Superior Core Design
The gap that suppresses the residual magnetism in the iron core is shielded with a stainless-steel plate. This will not wear out despite when under frequent cycling, ensuring a long service life.
