QBGZ*2X**0/*0

*0kV Mining Flameproof and Intrinsic Safety Dual Power Vacuum Electromagnetic Starter

Function:    

This product is used in underground coal mines, where there are mixed explosive gases, such as methane. It is used to control, protect and measure the power system, which is *-phase neutral point ungrounded, with rated voltage *0kV, rated frequency *0hz, and rated current up to **0A.

Features:

1. This product is composed of explosion-proof enclosure and functional core and is easy for maintenance.
2. Advanced CPU protection helps to protect the power system from damage of overload, electric leakage, insulation fault, short-circuit, and over or under voltage. Error self-inspection and inquiry functions are also available.
3. Circuit breaker can be switched on or off manually or automatically.
4. Remote control signal is intrinsically safe.
5. RS**5 interface is available.
6. Two high voltage vacuum contactors are mounted in the core. With different modes of wiring, it can be applied as: 

1. one with two output feeds. It can control and protect two motors simultaneously
2. two s with one output feed. It can be used together with soft starter to achieve one-in-one-out, one-in-two-out, or one-in-three-out.
