Contactors vacuum low-voltage KVNS 3-630/1,14. Vacuum contactors are characterized by small overall dimensions and small weight. The work resource many times is more than at similar type of electromagnetic contactors.

LLC NPP Energiya21 the new company the producer of low-voltage and high-voltage vacuum contactors of the KVN series 3 from 160 to 630A who go in exchange to electromagnetic contactors of the KT series. Kontaktora of the KVN type 3 productions of LLC NPP Energiya21 (TU U31.2-36816025-001:2010) of open execution with natural air cooling which are built in panel board and complete devices are intended for inclusion and shutdown of receivers of electric energy of 3 phase networks on rated voltage 380B, 660B and 1140B.

Vacuum contactors are characterized by small overall dimensions and small weight. The work resource many times is more than at similar type of electromagnetic contactors and costs of service at the same time are minimum as the work resource more than in the 3rd time of rather ordinary magnetic contactors shows experience.

Kvn3 are intended for work in the following modes: long, faltering and long, short-term, repeated and short-term. Are used: in crane panels, for switching of electric motors, in compressor and pump stations, and other switches.

Contactors vacuum low-voltage the KVN type 3 successfully passed tests in the territory of State Makiivka scientific isledovatelskogo institute on safety of works in mining industry (Scientific research institute Poppy) and according to test reports conform to requirements of such standards: GOST27863; GOST 24719; GOST 12.2.007.0; DSTU 3020.
