1140V Mining Flameproof and Intrinsically Safe Vacuum Electromagnetic Starter

QJZ***0(**5)/***0(**0)
***0V/ **0V Mining Flameproof and intrinsic safety Electromagnetic starter


Function: 
It is used in underground coal mines, where there are mixed explosive gases such as methane and other coal dust. It is used to control, protect and measure the *-phase squirrel-cage asynchronous motors and turns the directions at the stop, with rated frequency *0hz, rated voltage **0, ***0V and rated current up to **0A


Features:
Intelligent Single-Chip Microcomputer is used to protect the power system from the damage of overload, unbalanced phase, earth leakage, and short circuit with corresponding error information. 
 

1. Two operation methods are available:
2. Remote Control: A remote and a diode can be externally mounted in order to control the start and stop of the motor
3. On-site Control: Press the on the electromagnetic starter and control the start and stop of the motor
4. Manual emergency stop and reversing direction is available.
5. Information will be displayed including;
6. *-phase current, voltage
7. Switching-on operation, switching- off standby
8. Overload, unbalanced phase, short-circuit, elctric leakage
9. Error inquiry
