主要用途及适用范围
</h3>
<p class="p">
QBZ-200、120、80A/1140、660、380Z矿用隔爆型真空电磁起动器（以下简称起动器），适用于具有爆炸性气体（甲烷混合物）和煤尘爆炸性危险的煤矿井下，在交流50Hz，电压为1140V及以下的供电系统中，作为就地或远距离控制的矿用隔爆型三相鼠笼型异步电动机的起动、停止,并可在停止时进行换向,它特别适用于频繁操作，重负荷的煤矿机械设备中。

 QBZ电磁起动器产品特点
</p>
<p class="p">
该起动器的接触器是真空接触器，其灭弧介质是真空介质，因此其灭弧效果极佳，使其分断、接通能力增强，具有比空气接触器更加安全、可靠的特点。
</p>
<p class="p">
<span>该起动器采用的</span>JDB电机综合保护器，有过载、短路、断相、主回路漏电闭锁等功能
