At the place of its installation НКУ-РУСН is stationary and intended for indoor

operation, in the absence of vibrations or strokes. Environment should be

explosive-free, should contain no current-conducting dust, aggressive gases

and vapors in the concentrations reducing an insulation level within prohibitive

limits.


Design features

НКУ-РУСН is manufactured in the form of two-way servicing, arranged in one or

two rows, unite by a busbar bridge.

НКУ-РУСН is composed of the following cabinets: 0,4кВ input sections,

section breaker, distribution and general section units. A required number

of cabinets is determined by a diagram of primary connections, parameters

(dimensions) of automatic circuit breakers.

The cabinets of input, section breaker and distribution are completed with

automatic circuit breakers with a manual or motor drive of plug-in or pull-out

action. For mating НКУ-РУСН with a supply transformer piggyback cabinets are

manufactured.
