GB/T 22794-2017
ActiveType F and type B residual current operated circuit-breakers with and without integral overcurrent protection for household and similar uses
家用和类似用途的不带和带过电流保护的F型和B型剩余电流动作断路器
Application Summary AI generated
This standard specifies technical requirements and test methods for Type F and Type B residual current circuit-breakers, which are designed to detect and interrupt specific types of fault currents, including smooth DC and mixed-frequency AC/DC residual currents. It applies to household and similar electrical installations, such as residential buildings, commercial premises, and light industrial environments, where enhanced protection against electric shock and fire hazards is needed for circuits supplying equipment like variable frequency drives, inverters, or charging stations.
