QJZ1-1600/1140(660)Z9-12
Mine Explosion-proof and Intrinsically Safe Compound Vacuum Electromagnetic Actuator


Applications
The actuator is mainly used for control of starting, stopping, reversion and double-speed switch of 12 mine explosion-proof three-phase AC induction motors or six mine explosion-proof three-phase AC double-winding double-speed motors in the power supply circuit, with the AC frequency of 50Hz, rated voltage of 1140V or 660V. Besides, it’s suitable for protection of the electromotor and relevant circuit and reversion when it stops working.


Features
1. Chinese liquid crystal display with15 × 8 Chinese character lattice.
2. The intrinsically safe operation control through the leading circuit, remote control, and self-control of the machine are all available.
3. It can provide protection from over current, short circuit, undervoltage, phase failure, leakage lockout, and operation overvoltage.
4. It has the function testing, display, communication, fault inspection, and fault memory
.5. The parameter of those protection functions is capable of selection, adjustment, and opening or closing in the menu.
6. It has advanced RS485 or CAN interface communications networking function. It can be connected to the LAN or the Internet, to facilitate remote monitoring and control. Besides, it has the functions of remote control, remote adjustment, remote detection and remote communication.
