Mine Explosion-Proof and Intrinsically Safe Multi Circuit High Voltage Vacuum Electromagnetic Combination Switch

QJZ3-2400/1140(660)-8ML  mine explosion-proof and intrinsically safe type multi-loop  vacuum electromagnetic starter , it is applicable to the mine with explosive gas and coal dust. In the circuit with AC 50Hz and rated voltage of AC 1140 (660) V, it can control and protect the starting and stopping of 8  or less three-phase squirrel cage asynchronous motors at the same time, and can change the phase sequence when stopping. It is especially suitable for centralized monitoring of mining, transportation, mining and other working faces with concentrated power load.

Mining explosion-proof and intrinsically safe type multi-loop high-voltage vacuum electromagnetic starter is suitable for coal mine AC 3300V, frequency 50Hz, three-phase neutral point unearthed power supply system, local or remote control of three-phase asynchronous electric drive, to realize the centralized control of shearer, scraper conveyor, crusher, transfer machine, pumping station and other equipment in comprehensive mechanized coal mining face.
