 <description><![CDATA[1500/380*1.732=2.2
2.2*0.85=1.9
1.9*1.25=2.5

选择2.5A的热继保护就够了。真是烧的冤啊。]]></description>

 <description><![CDATA[一般来讲电机烧了,热继是不会跟着烧的,你要查查什么原因,电机都烧了这问题就不小了!]]></description>

 <description><![CDATA[电机是怎么烧掉的，首先你要查清楚，对于断路器不跳的问题是不是你把电流选大了，不是的话肯定是质量的问题，如果是电机质量不好，断路器也不会跳的。]]></description>
