Electrical life is an important parameter to estimate the reliability of relay. Non-closing and Non-opening caused by arc erosion and/or material transfer are two primary contact failure modes in relay. Load current has great influence on the two modes and the life of relay. In this paper, load current stress accelerated life tests were carried out by a life test system designed for relay. During life test, the characteristic parameters such as contact resistance, closing time and opening time of the relay were measured for each operation to identify if the relay samples failed or not, thus the mechanisms and the modes of contact failures were determined. In addition, A Weibull statistical analysis was adopted to check the consistency of failure mechanisms under different load current stress. Finally, a statistical model for estimating the life during DC load current stress and investigating the acceleration factors of high current stresses was built.
