Mining Explosion-proofa Reversible Vacuum Electromagnetic Starter

We are engaged in exporting and supplying excellent quality Mining Explosion-Proof Reversible Vacuum Electromagnetic Starter in Hefei, Anhui Province, China.

1. Use
The device is used in coal mines containing explosive gas (methane) and coal dust.A In the three-phase neutral power supply system with rated voltage 1140V, 660V or 380V, AC 50Hz, rated current 200A, it can control theA start or stop of the three-phase asynchronous motor closely or remotely, and can change the phase sequence after the load motor stops.

2. Features
a. The main circuit adopts vacuum contactor, having long life and reliable performance.
b. Using self-developed WTB-1 type microcomputer monitoring device, comprehensive functions, stable and reliable.
c. Can be used by a single one or program-controlled combination.
d. Having a RS485 interface realizing the four distance functions: "remote regulating", "remote measurement", "remote signaling", "remote control", becoming an important part of digitized mines.
e. Using simple control lines and the fast-openA doorA structure, easier to maintain.
