Assembly of the equipment is made with use of the vacuum interrupters of in-plant production.
The automatic vacuum switch such as ВВА-1,14 is intended for current conduction in a nominal mode to protect at short circuit currents, overload currents and invalid voltage reductions and also for infrequent operative connect and disconnect of electric power receivers.
The switch is delivered both with the block of microprocessor electronic current protection and also without it.

Contactors КВТ - 1,14 (3-d, 2-nd unipolar, reversive contactors of horizontal and vertical types, plug-in contactors and contactors with electronic current relay) and contactors of special (mining) modification for mining industry are intended for connect and disconnect of electric power receivers, and also for reversing of electric circuits (reversive contactors) and protection of the electric motors from overload currents and breakage of phases, non balance (contactors with electronic current relay).

Advantages of vacuum equipment:

- Long service life;
- High switching resistance;
- Explosion and fire safety;
- Absence of an open electric arc;
- Ecological safety;
- Simplicity of service;
- Small overall dimensions and weight.

The system of a quality management is certificated by "Centrocert" institution in the system of DAR-TGA and corresponds to requirements of the standard ISO 9001-2000.
