Use: The mining explosion proof intrinsically safe reversible 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 the power supply of AC 50Hz, power grid voltage is 1140V,660V or 380V, current range is30~200A.lt can be directly used to control or remote control the start and stop the mining explosion proof three-phase asynchronous motor.
We are paying effort to prompt the development of explosion proof industry.We will bring innovation and surprise for the industry.
We are ready to face the challenge
Making our dream come true....
