GLVAC AC Vacuum Contactor CKJ5, 160A/1.14kV
GLVAC CKJ5-160/1.14 AC vacuum contactor is suitable in electrical system rated operational voltage up to 1140V to make or break remote motors or system, suitable for the control of AC motor’s frequent, widely used in power systems, oil fields, chemical industry, mine, metallurgists and electrified railway, etc.
- Vacuum contactors use vacuum interrupter as switching elements
- The main circuit moveable and stationary contacts are sealed in the vacuum where the atmospheric pressure is lower than 1*10-2 Pa.
- Vacuum medium has good isolation and arch extinguishing ability, therefore the vacuum contactor is characterized as high isolation voltage
- Small contact stroke
- Low contact wear
- Long life
In the light of mentioned specifications, this vacuum contactor provide the best solution for your switching applications especially at high voltage parameters. For more technical features, you can see the specifications table of CKJ5, 160A/1.14kV below.
