Underground Explosion Proof Switchgear 400A 1140V For Overload

Description:

Combination switch, is used to control lighting and lighting signal device of multifunctional combined switch and other accessories. It is handle type, usually mounted on the steering wheel of the steering column, in order to facilitate the pilot operation. Usually, the combination switch points two handles and a button.

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. 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.
