欠电压脱扣器至少包含动、静铁芯和线圈,采用电子线路控制的脱扣器还包含电子线路一部分。在国内一、二代万能式断路器白小姐三肖选一肖上面采用直接电源控制的助吸式欠电压脱扣器构造,因为运行空气污染严重或助吸构造推力歪斜时,会导致动静铁芯吸合不靠谱,运行时出現交流噪声。这时候线圈电流量会增大,铁芯铁损加重,将造成线圈自主发烫损坏。在电子线路控制板一部分,因为采用了非常复杂的构造,欠电压脱扣器能进行铁芯自动吸合功能。在2000年前的DW45欠电压控制一部分就采用此类方式,因为设计中沒有考虑到线圈反电势对于电子元件的影响,常常会引起电子器件輸出一部分的好多个电子器件损坏。另一个在这类设计中,因为采用了较多的电子元件,因而故障点增加,对电子元件要求高,发生故障的几率大得增加。
