KVT series vacuum contactors, open type with natural air cooling, designed for integration into complete devices, intended for use in starters, control stations, for switching inrush and cut-off currents of squirrel-cage induction motors and other power consumers in remote electric drive control systems with heavy-duty operation in AC circuits 50-60 Hz, voltage up to 2500 V.
Thanks to the high dielectric strength of the vacuum gap and the absence of a medium supporting arc combustion, the electric arc breaks up and extinguishes.
* High switching and energy endurance;
* High short-term load capacity for heavy starts;
* Absence of an open electric arc and combustion products;
* High speed of operation;
* Maximum fire and explosion safety;
* Low noise level during operation.
