Scope

Main technical content: This standard specifies the terms and definitions, classification, basic requirements, characteristics of RCBOs, marking and other product information, standard working conditions for use and installation, structural and operational requirements, testing, packaging, transportation and storage, and quality commitments for RCBOs. The RCBOs specified in this standard are applicable to AC rated frequencies of 50 Hz, 60 Hz, or 50/60 Hz, with a rated voltage not exceeding 440 V, a rated current not exceeding 125 A, and a rated short-circuit capacity not exceeding 25,000 A. The RCBOs specified in this standard are designed for household and similar applications with overcurrent protection, and their operating function is independent of the power supply voltage. The RCBOs specified in this standard are used for indirect contact protection of humans, in which case the exposed conductive parts of the equipment should be connected to a suitable grounding electrode; they can also be used for overcurrent protection of building and similar line equipment, and to provide protection against fire hazards caused by grounding fault currents persisting due to the failure of overcurrent protection devices to operate. The RCBOs specified in this standard are suitable for use by non-professionals and do not require maintenance. The RCBOs specified in this standard are intended for use in environments with a pollution level of 2. The RCBOs specified in this standard are suitable for isolation and are suitable for use in IT systems. The RCBOs specified in this standard are enclosed type (no need for a suitable enclosure). The I2t characteristics of the RCBOs specified in this standard comply with the requirements of energy level 3. This standard does not apply to: - RCBOs used for motor protection; - RCBOs with a setting current value that can be adjusted by the user during use. RCBOs using batteries are not included in the scope of this standard.
