Scope

This standard specifies the terms and definitions, classification, circuit breaker characteristics, product information, normal operation, installation and transportation conditions, structural requirements, performance requirements, and test methods for low-voltage circuit breakers used on the AC grid-connected side. This standard applies to AC circuit breakers with a rated voltage not exceeding 1000V and a frequency of 50Hz/60Hz, used in AC grid-connected low-voltage circuit breakers in new energy power generation systems, hereinafter referred to as "circuit breakers". The circuit breakers specified in this standard are suitable for photovoltaic power generation systems and wind power generation systems (referred to as photovoltaic systems and wind power systems) connected to the grid at the AC output end. Note: The grid voltage to which the circuit breaker is connected can be 220/380V, 380V, or it can be accessed through a step-up transformer to a grid with voltages of 6kV, 10kV, 35kV, and above.
