* Rated voltage up to 12 kV , indoor type ,3 pole.
* Use for medium motors, transformers and capacitors.
* Safe and reliable with the contactor enclosure completely sealed and low SF6 gas pressure 2.5 bar.
* Divided into separate compartments and specialization to improving the safety and continuity of operations. There are safe coverto reduce pressureand exhaust gas in case of arc. Contactor use SF6combine modern interrupt arc techniques and rapidly recover dielectric , limited  abrasion of contact.
* High mechanical endurance 100000 -300000 times.
* High electrical endurancewith SF6 technique to reduce the  arc time and arc length.
* Voltage pulses when switching is low to prevent the destruction of insulation of the motor windings.
* Be able to select the type of contactor is kept by mechanical or electronic key
* Be able to continuously monitor SF6 gas pressure ( depending on requirements ).
* It is possible combine with fuse to enhance security features.
* Using modular equipment and standardized convenient for assembly and maintenance
* Integrated into a row of panel to reduce the size
* Capable of remote control through integrated monitoring systems such as SCADA or DCS
