Scope
Scope: This standard specifies the terms and definitions, symbols, classification, characteristics, product information, normal operation, installation and transportation conditions, structural and performance requirements, and test methods for intelligent AC universal circuit breakers (hereinafter referred to as circuit breakers). This standard applies to circuit breakers with a rated frequency of 50/60Hz, a rated working current not exceeding 8000A, and a rated working voltage not exceeding 690V AC. Circuit breakers with a rated voltage higher than 690V AC but not exceeding 1500V AC can be tested according to this standard. The circuit breakers covered by this standard shall be equipped with an electronic controller (hereinafter referred to as a controller), which has basic overcurrent protection functions, a reasonable human-machine interface, self-diagnostic and processing functions for faults, and other optional functions that fully leverage the advantages of electronic technology.
