GLVAC AC Vacuum Contactor CKJ5-160/1.14
GLVAC CKJ5-160/1.14 AC Vacuum Contactor - 160A 1.14kV
The **GLVAC CKJ5-160/1.14** is a robust AC vacuum contactor designed for frequent switching and control of AC motors in power systems with rated operational voltages up to 1140V. Utilizing advanced vacuum interrupters, the main contacts are hermetically sealed in a high-vacuum environment (lower than 1*10-2 Pa), providing superior isolation and exceptional arc extinguishing capabilities. Characterized by a small contact stroke, minimal wear, and an extended mechanical life of one million cycles, this contactor offers a reliable and stable solution for demanding industrial sectors including mining, oil fields, chemical processing, and electrified railways.
