RGC-1型交直流电磁接触器适用于铁路电力机车、内燃机车、动车组等牵引电机主电路的接通和关断。

该接触器采用欧洲先进技术，电磁驱动，结构紧凑，安全可靠，使用寿命长，少维护、免维修。

该接触器带有过电压抑制器，其线圈不会在110V控制回路中产生反电势，因此，控制回路不需加装其它过电压抑制装置。该接触器具有优越的磁吹灭弧性能，只有在接触器分断拉弧时灭弧线圈才导通，在正常工作状态下，灭弧线圈不导电，大大降低了电耗和发热。

RGC-1 AC-DC electromagnetic contactor is for switching on and off the main circuit of traction electric machine for railway electric locomotives, diesel locomotives, and motor train unit etc.

With European advanced technology and electromagnetic drives, the contactor is safe and reliable with compact structure, long life, low maintenance, and repairing-free.

As the contactor, with the over-voltage suppressors, the coil of which will not produce back EMF in 110V control loop, there is no need to add other over-voltage suppression devices in the control loop.The contactor has excellent performance of magnetic blast arc quenching. The blowout coil is conductive only when the contactor breaks arcing and is not conductive in normal working condition, therefore, heat and power consumption can be greatly reduced.
