mine explosion proof and intrinsically safe type assembly switch

Purpose

It is ideal for mines having explosive gases (Methane) and coals, and it is used in AC *0Hz, ***0V power supply circuit. It can control start, stop, reverse rotation and double-speed switching of many *-phase AC asynchronous inductance motors or many AC double-winding and double-speed motors, and it also can protect motors and their power supply circuits. Therefore, when it is attached in KJ**4 mine electric power automatic control and comprehensive measurement and monitor system to realize automatic control on power supply equipments in mining area. The starter has all Chinese LCD touch screen display that has highly stable performance and is highly reliable for perfect man-machine conversation function.
