Switch-disconnectors connected VR intended for inclusion, deletion and disabling AC rated voltage up to 660 V rated frequency 50 and 60 Hz DC rated voltage up to 440 V devices distribution of electric energy, as well as AC voltage 1140 Frequency 50 and 60 Hz without load.

Connected VR classified:

1. Nominal current.

2. The number of poles

3. In view of the arm of the actuator;

- bokowa, is mounted directly on the apparatus, provides the degree to protect R,

- lateral offset is set on the side of the Cabinet, provides a degree of protection R and IP54,

- front offset is installed on the front surface of the Cabinet, provides the protection level is IP00,

- front rotary handle - provides protection R;

4. The location of the plane attach external clamps.

5. The presence or absence of arc chambers.

6. The presence or absence of auxiliary contacts

The main components of the apparatus are the movable and stationary contacts. A set of movable and stationary contacts since housing is a package. Packs tight hairpins. The number of packets corresponds to the number of poles plus one the building, which houses the locking mechanism that serves to secure the arm drive in the "enabled" and "disabled". Movable contacts mounted in plastic shaft, the rotation of which arm actuator wiring the position is opening and closing the contacts. In the design apparatus applied contact system blade type with visible double break chain. Using double-circuit, large solutions of contacts and arc chambers provides effective damping of the electric arc when switching loads, which prevents premature and excessive wear contacts.

The design of the contact pins meets the requirements of GOST 24753-81 and provides the joining of copper and aluminium conductors and cables, terminated or cable lugs or the contact clamps, and tires with threaded connections
