QJZ-4×400/1140(660)
Mining explosion-proof and intrinsically safe type vacuum combination switch starter
Application
This equipment is suitable for mines containing explosive dangerous gases and coal dust. In the line of AC 50Hz and rated voltage AC 1140 (660) V, it can start and stop the logic of less than 4 three-phase squirrel cage asynchronous motors at the same time. Control and protection, and can change the phase sequence when stopped. It is especially suitable for centralized monitoring of power, mining, transportation, coal mines and other working faces.
