QJZ1-1200/1140(660)-4
礦用隔爆兼本質安全型組合式真空電磁起動器
Mine Explosion-proof and Intrinsically Safe Compound Vacuum Electromagnetic Actuator

適用范圍及用途
起動器主要用于交流頻率50Hz、額定電壓1140V或660V供電線路中,對4臺礦用隔爆型三相交流感應電動機或兩臺礦用隔爆型三相交流雙
繞組雙速電動機的起動、停止、反轉及雙速切換進行控制；同時對電動機及其有關線路進行保護；并可在停止時進行換向。

Applications
The actuator is mainly used for control of starting, stopping, reversion and double-speed switch of 4 mine explosion-proof three-phase AC induction motors or two
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.

主要特征
