Continue Cycling to Relay Failure
The testing objective is to verify proper relay function for a given number of consecutive and cumulative cycles under
both normal and abnormal conditions in a variety of load switching applications. The life rating of 40K cycles minimum
was calculated with 95% Weibull reliability.
