Product Description

Mining explosion-proof vacuum electromagnetic Starter(Intelligent)

1. Applicable Scope
The device is used in coal mines containing explosive gas (methane) and coal dust. In the three-phase neutral power supply system with rated voltage 1140V,660V or 380V ,AC50Hz, rated current 80A, 120A,it can control the start or stop of three-phase asynchronous motor closely or remotely ,and can change the phase sequence after the load motor stops.

2. Product Feature 
The main circuit adopts vacuum contactor, having long life and reliable performance. 
Using self-developed WTB-1 type microcomputer monitoring device, comprehensive functions, stable and reliable. 
Can be used by a single one or program-controlled combination. 
Having a RS-485 interface, realizing the four distance function: remote regulating, remote measurement, remote signaling, remote control, becoming an important part of digitized mines. 
Using simple control lines and the fast-open door structure, easier to maintain.
