Distribution units series of 85(11):

Distribution units are intended for the reception and distribution of electrical energy, protection of the direct current electrical installations with voltage up to 220 V and alternating current up to 660 V with a frequency of 50 Hz, during overloads and short circuits, as well as for temporary (not more than 6 per hour) on/off switchings of electrical circuits and starts of asynchronous electric motors, and provide protection against electric shock.
Cabinets are designed for installation in industrial, residential, household and public facilities. By agreement with the customer, it is possible to install residual current devices (RCD) on the feeders. Cabinets are available in wall-mounting and floor-standing versions.

The cabinet is designed to operate under the following conditions (GOST 15150-69):

– on the influence of climatic factors of the external environment: in macroclimatic regions with a temperate climate (version У);
– environmental classes are 1, 3, i.e. outdoors, under a canopy, indoors with natural or artificial ventilation, as well as in a room with high humidity;
– on the corrosion resistance: in the atmosphere of industrial facilities, these cabinets should be with a degree of protection IP54, version У1;
– the height above sea level is not more than 2,000 m; if an altitude of more than 1,000 m, the nominal operating current of the cabinet shall be reduced by 10%.
