Application Summary AI generated

This standard specifies the technical requirements and test methods for residual current circuit-breakers (RCCBs) that operate independently of line voltage, meaning they can still trip to protect against electric shock even when the supply voltage is lost. It is applied in household and similar electrical installations where RCCBs are used without integral overcurrent protection, ensuring reliable leakage protection in environments such as residential buildings, offices, and small commercial facilities. The standard is particularly relevant for manufacturers and testing laboratories verifying compliance with safety regulations for devices that must function regardless of power supply conditions.
