Product Description

 

Mine Use Vacuum Insulated Switchgear High Voltage For Overload

 

 

Description:

 

QJZ-400/1140(660) mine use flame-proof and intrinsically safe vacuum electromagnetic starters are suitable for underground mines containing explosive gas (methane) and coal dust. They start and stop directly or remotely motors with rated current up to 315 A ( 400A) on the power supply system of a. C. 50Hz, 1140V or 660V, and they provide protection of motors and their power supply lines.
 

 

Competitive Advantage:

 

16 bit micro-processor for intelligent control, Chinese(English) character LCD, current detection and fault output, optional data transmission interface (RS485 or Device Net) and optional built-in FLEX I/O for remote control.
