CKJ5-1140V Indoor vacuum contactor 1140V (fixed)

CKJ5 series vacuum AC contactors are particularly suitable for forming flameproof vacuum electromagnetic starters and comply with standards such as GB/T 14048.4 and IEC60947-4-1. Because the main contact works in a high vacuum environment, it has the advantages of no exposed arc, small size, light weight, long life and long maintenance cycle.
