Product Introduction of Mining Explosion-proof Vacuum Feeder Switch


Features:


It can control restrict current start and voltage incline electric wave


Function of pulse flounce sudden: use for super high stillness friction load.


Automatic protect function: Automatic protect function of over voltage, lack of voltage, phase-failure, creepage, over current, short-circuit, zmwm02 over hot, long start time, too long restrict current time Can select data traffic linker connect with control system; can fit out RS-485 data traffic linker according to user’s requirement.


 


 


Application:


The series starter is mainly used to control of mining flame-proof three phases asynchronous motor with frequency 50Hz, rated voltage 660V or 1140V, rated power 60 to 400 kw., It can make motor always continually starting any instance, protect dragging system, reduce impact to electricity meshwork made by start current, protect reliable starting of motor. It can be directly or remotely controlled, and make reversing when controlled motor stops. The starter with function of protect voltage-lost, voltage-absent, short-circuit, overload, phase-failure. creepage closedown and display of related fault and work state of power supplying and running.
