Vacuum contactor KVT-1.14-2.5/250-3 U3 3P 250A coil 220V AC 4NO+3NC IP00 without relay Elektrotekhnik ET557368

KVT series open-type vacuum contactors with natural air cooling, designed for installation into complete devices, intended for use in starters, control stations, for switching the inrush and disconnection currents of squirrel-cage induction motors and other electrical receivers in remote electric drive control systems with a heavy duty cycle in an AC circuit of 50-60 Hz, with voltage up to 1140 V. Due 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; * Maximum fire and explosion safety; * Low noise level during operation.
