GB/T 16917.22-2008
ActiveResidual current operated circuit-breakers with integral overcurrent protection for household and similar uses (RCBO) - Part 22:Applicability of the general rules to RCBO functionally dependent of line voltage
家用和类似用途的带过电流保护的剩余 电流动作断路器（RCBO） 第22部分：一般规则对动作功能与电源电压有关的RCBO的适用性
Application Summary AI generated
This standard specifies the technical requirements and test methods for RCBOs whose residual current tripping function depends on the line voltage, ensuring reliable operation under specified voltage conditions. It is applied in household and similar electrical installations to protect circuits against both overloads, short-circuits, and earth faults, particularly where the protective device's functionality is tied to the availability of the supply voltage.
