Mining Dual Power Vacuum Electromagnetic Starter for Fan

Product Description

QJZ*2X**0(*0)SF

***0V/**0V Mining Flameproof and intrinsic safety Dual Power Vacuum Electromagnetic Starter for Fan

Function: 

It is used in underground coal mines, where there are mixed explosive gases such as methane and other coal dust, with rated frequency *0hz, rated voltage **0, ***0V. It helps to start and stop the *-phase squirrel cage motor, and it can also reverse the direction of the motor at the stop.

Features:

It is frequently used for single or dual fans environment. The starting and stopping of the two motors can be delayed to minimize the damage to the power system. It is designed with two separate explosion-proof cavities, so that if any error occurs in one cavity, it will automatically switch to the alternative one. Inspection can be done while fan is working. 

Intelligent protection helps to do the parameter adjustment and information inquiry. It also protects the power system from electricity leakage, low voltage, over voltage, *-phase unbalance, overload, short-circuit, loss of phase and wind power alarm.
