QJZ3 Mining Explosion Proof Intrinsically Safe Vacuum Electromagnetic Starter

QJZ3 Mining Explosion Proof Intrinsically Safe Vacuum Electromagnetic Starter

Use
The mining explosion proof and intrinsically safe vacuum electromagnetic starter is used in coal mine or places where are filled with explosive gas mixture such as methane, coal dust and so on. In power supply of AC 50Hz, voltage is 1140V, 660V, or 380V, current range is 30~200A, it can be directly used to control or remote control the start and stop mining explosion proof type three-phase asynchronous motor and it also can be used phase exchange when the motor stops.
