Vacuum Contactor (JCZ8C-24kV )
This series of high-voltage vacuum contactors is suitable for use in 24KV power systems or plateaus and high altitude above 4000 meters. This series of high-voltage vacuum contactors has a large stroke and strong breaking ability, small bounce and stable opening and closing bounce. The three have good periodicity, especially suitable for switching the load of the capacitor bank. There are three types of models: electromagnetic holding type, mechanical holding type, and permanent magnet mechanism type, and the secondary control is simple and reliable.
The metal frame is firmly integrated into one, which is safe and reliable.
The mechanism has a large stroke, strong breaking ability, small bounce and stable opening and closing bounce.
The three have good periodicity, especially suitable for switching the load of the capacitor bank.
