Pilz PA-1S/1/400VWS/1U 

Pilz PA-1S/1/400VWS/1U  1、过载保护负载的接头不太牢固，尤其是通过人工接线的部分电器，尤其要注意这点问题。也有在线路中负载电流如果超过安全电流的时候，空气开关为了保护线路的安全而自动跳闸。

2、或许是空气开关的电流值太低，以致于不能够满足负荷也会造成空气开关跳闸。换一个负荷大一点的空气开关就好了。

3、空气开关在工作的过程中出现短路的问题，首先要检查电气插头是不是处于干燥的状态。

4、如果空气开关出现了漏电的现象，检查是否线路老化造成了零线和火线都带电，这时一定要找专业人士来解决，以免盲目操作发生危险。

5、欠压或者过压都会造成空气开关跳闸，一般这种情况会出现在用电高峰期的老房子中。

6、如果接头、线路等都没有问题，就要去检查是不是空气开关的质量不行。空气开关质量的好坏与否也会造成跳闸现象的发生。
