Description

Switches disconnectors of the BHK 250 - 1600A/series ~ 660B/~ 380B/~ 440B/~ 220B


Structure of indetifikatsionny designation PHOTO 2


Assignment:
Switches disconnectors (load-breaking isolators) of the VNK series are intended for non-automatic switching of rated power electric chains of alternating current and 440 V of a direct current in devices of distribution of electrical energy, can be used as the master and emergency switches

Are established:
- Directly on building constructions
- In land stationary complete devices
- On load-lifting cranes, the body of roller conveyors and the rolling equipment
- In bodies and under bodies of electric locomotives and locomotives, cars of railway transport, on flat-cars
