Application
QJZ3-□/□N mining ex-proof intrinsic safety reversible vacuum electromagnetic starter (hereinafter: starter) is applicable in coal mine or places where are full of explosive gas mixture such as methane, coal dust and so on. In the power supply of AC 50Hz, power grid voltage 1140V, 660V or 380V, current 30-200A, it can be used to directly control or remote control the start and stop the mining ex-proof three-phase asynchronous motor.
Features
Main circuit of this series product adopts vacuum contactor, without arc, long life and high reliability.
Adopts JDB motor integrated protector with complete protection function.
There is reliable electric interlocking and machinery interlocking between two contactors which is connected in forward and reverse direction.
Simple structure, less maintenance.
