It is in high demand among those living in the country (house, cottage), owners of small production sites, workshops, as well as owners of “demanding” equipment - power tools (compressors, pumping stations, HVAC equipment, etc.). Installation in a three-phase network for each phase will provide 60 kVA of power, and thereby eliminate the possibility of complete loss of the network. When connecting a three-phase load (machines, motors, etc.), it is enough to additionally install a phase control relay. The ability to connect a large number of pieces of equipment, electrical wiring throughout the house - makes this model indispensable for suburban life. The SUNTEK 20000VA voltage relay of the relay type possesses all the qualities of the SUNTEK relay line - reliability, simplicity, quality for reasonable money.
