Flame Proof 400A 1140V High Voltage Vacuum Switchgear For Mine

Description:

QJZ-315/1140(660) Z mine use flame-proof and intrinsically safe vacuum electromagnetic starters are suitable for underground mines containing explosive gas (methane) and coal dust.Along the axis of combination switch 4 respectively installed the three-layer switch components from bottom to top, each layer has a dynamic contact 8, a pair of static contact and a pair of terminal 1, 9 layers respectively control the flux and a branch off, form the combination switch triode. 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.
