Product Description
Mining Explosion proof Starter QJZ series(2-10circuits/3300V)

1. Function

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