Vacuum interrupter for contactorVTJ4340AZKTJ 400/12-6.3ZKTJ 630/12-6.3  Vacuum Interrupter for ContactorVacuum arc extinguishing chamber, also known as vacuum switch tube, is the core component of the high voltage power switch, its main role is to cut off the arc and inhibit the electric current by its high inside insulation performance to avoid accidents.Wuhan Feite Electric brand vacuum arc extinguishing chamber adopts a corrugated ceramic insulation shell, copper tungsten tungsten carbide alloy materials contact, using advanced one exhuast technology process makes the vacuum interrupter has the advantages of small volume, high insulating level, low closure value, long service lifetime, easy-maintenance, explosion-free, low noise, low maintenance costs, reliable operation and non-pollution etc.. The vacuum arc extinguishing chamber mainly been used in power transmission and distribution control system. It is also can be used in metallurgy, mine, petroleum, chemical industry, railway, broadcasting, communications, industrial high frequency heating power distribution system.Wuhan Feite Electric vacuum arc extinguishing chamber for vacuum contactor rated voltage is 1.14~40.5kV, rated current is 630A~1250AMain Technical Data  ELECTRICAL RATINGS(3PHASE) SYMMETRICAL BASIS 1.Rated Voltage12KV2.Rated Current400/630A3.Rated Frequency50Hz 4.Rated Short-time Power Frequency Withstand Voltage(1min) 70KV5.Rated Lighting Impulse Withstand Voltage107KV6.Rated Making Current6.3KA7.Rated Breaking Current,Max5.0KA8.Rated Breaking Current,Min125A9.Rated Making Current,Limit6.3KA10.Rated Short-time Withstand current6.3KA11.Rated Duration of Short-circuit4s12.Mechanical Life30×times13.Electricity Life AC-325×times14.Electricity Life AC-410×times15.Rated Contactl Stroke8±1mm16.Contact Closing Force Due to bellows and atmosphere120±50N17.Counterforce at rated contact stroke190±60N18.Circuit resistance at rated contact atmosphere force≤45 µ 19.
