It is ideal for mines having explosive gases(Methane)and coals,and it is used in AC 50Hz,1140(660)V power supply circuit,
it can controlstart,stop,reverse rotation and double-switching of 6-12 3-phase AC asynchronous inductance motors or 3-6 AC
double-winding and double-speed motors,and it also can protect motors and their power supply circuits.Therefore,when it is
attached in KJ2000 mine electric power automatic control and comprehensiv measurenent and monitor system to realize
au-tomatic control on power supply equjpments in mining area.The starter has all Chinses LCD touch screen display that
has highly stable performance and is highly reliable for perfect man-machine conversation function.
