Product performance and standards: The manufacturer's products should comply with national standards, and key parameters such as rated current and short-circuit fault current should be accurately labeled and tested. The product performance, such as action speed and lifespan, should meet the standard requirements, with particular attention paid to testing data on failure rate and service life.
