product introduction
Product Details

1. Function

It is ideal for mines with explosive gases(Methane)and coals, and it is used in AC50Hz,3300Vpower supply circuit, it can control start, stop, reverse rotation and double-speed switchingof 2-10 sets of three phase asynchronous induction motors or 1-5 sets AC double-windingand 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 comprehensivemeasurement and monitor system to realize automatic control on power supplyequipments in mining area. The starter has all English LCD touch screen display that hashighly stable performance and is highly reliable for perfect man-machine conversationfunction.
