Scope
Scope: This standard applies to low-voltage distribution systems with a rated frequency of 50 (60) Hz, a rated working voltage of 220 (230) V, and a rated working current of no more than 100 A, which are used in intelligent distribution boxes assembled from various devices such as switchgear, circuit breakers, circuit board protection devices, measurement displays, and indicator lights. Main technical content: - Centralized control (1st generation) product series: Provides real-time "intelligent display, monitoring, and protection" for "overvoltage, undervoltage, and leakage current". - Decentralized control (2nd generation) product series: Provides separate real-time "intelligent display, monitoring, and protection" for "overvoltage, undervoltage, leakage current, short circuits, and overloads".
