Electrical Low Voltage Vacuum Contactor 1140V , AC Contactor Switch 400A

Vacuum contactor CKJ5-250Y/1140 type AC contactor Application Vacuum contactors utilize vacuum bottle encapsulated contacts to suppress the arc. This arc suppression allows the contacts to be much smaller and use less space than air break contacts at higher currents. As the contacts are encapsulated, vacuum contactors are used fairly extensively in dirty applications, such as mining.Vacuum contactors are only applicable for use in AC systems. The AC arc generated upon opening
