Summary:In this paper, the reliability ofcontactor relay is studied. There are three main parts about reliability test and analysis. First, in order to analyze reliability level of contact relay, the failure ratio ranks are established as index base on the product level. Second, the reliability test method is put forward. The sample plan of reliability compliance test is gained from reliability sample theory. The failure criterion is ensured according to the failure modes ofcontactor relay. Third, after reliability test experiment, the analysis of failure physics is made and the failure reason is found.
