Vacuum contactor KVT(M)-1.14-5/800-3 U3 3p 800A cat. 220V 3NO+3NC IP00 non-reversing without relay with magnetic hold Electrotekhnik ET013987

We manufacture and supply. The product is certified. KVT vacuum contactors, open type with natural air cooling, designed for integration into complete units, are intended for use in starters, control stations, for switching the 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 50-60Hz circuits, up to 1140V. Vacuum contactor is the next stage in the development of popular industrial air electromagnetic contactors. Unlike air contactors, where the main contacts are switched in an atmospheric environment, the contacts of KVT vacuum contactors are located in hermetic vacuum flasks. Due to the high dielectric strength of the vacuum gap and the absence of a medium that supports arc combustion, the electric arc breaks up and extinguishes. However, a special advantage of KVT vacuum contactors is their at least doubled electrical endurance compared to air contactors. Therefore, they are suitable for frequent switching operations in S1/mixed duty cycles. *Purpose of KVT vacuum contactors:* • switching in short-time and intermittent, continuous and intermittent-continuous operating modes of electric motors and other powerful inductive loads with a rated operating voltage of up to 1140V AC 50Hz; • switching loads in industrial environments with a high concentration of dust and gases, to meet fire and explosion safety requirements; • switching capacitive load in UKRM reactive power compensation units; • controlling remote loads with infrequent maintenance cycles in hard-to-reach locations. *Application area of KVT vacuum contactors:* • industrial industry, compressor-pump units, lifting and crane units; • metallurgical industry; • oil and gas industry; • mining industry; • urban and railway rolling stock; • urban, industrial power grids and road infrastructure.
