The national standard gb51348-2019 stipulates that the terminal circuit of storage warehouse, electric vehicle charging and other places shall be equipped with current limiting electrical fire protector. Electrical fire current limiting protector can overcome the disadvantages of large short-circuit current, long time to cut off short-circuit current, large arc spark during short-circuit and short service life of traditional circuit breaker, air switch and monitoring equipment. In case of short-circuit fault, it can quickly limit short-circuit current at microsecond speed to realize arc extinguishing protection, so as to significantly reduce electrical fire accidents, Ensure the safety of personnel and property at the place of use.
