Vacuum contactors like "KVV 3" of production of LLC NPP Energiya21 (TU U31.2-36816025-001:2010). Open execution with natural air cooling, 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 10KB.
Vacuum contactors are characterized by small overall dimensions and small weight. The resource of work is much higher than at similar type of electromagnetic contactors and costs of service at the same time are minimum.
Are intended for work in the following modes:
- faltering and long
- repeated and short-term.
- in crane panels,
- for switching of electric motors,
- in the compressor - pump stations,
