Electromagnetic contactors of KTI series are intended for use in control circuits for start and stoppage of 3-phase squirrel-cage induction motors supplied from mains with rated voltage up to 660 V, and also can be used for switching on/off other electrical units: lighting, heating devices, various inductive loads.
Used with fans, pumps, furnaces, beam cranes and automatic load transfer systems.
Simple design provides for easy maintenance of components.
The base is made from aluminum shape that ensures increased robustness and lesser weight compared with similar designs.
Wide range of optional devices readily available in the stock (PKI contact attachments, PVI time-delay attachments).
Broadened range of offered KTI electromagnetic contactors as compared to the similar products from domestic manufacturers on Russian market.
