This standard applies to mobile electrical accessories for household and similar purposes, including automatic breaking and non automatic (manual) reset overcurrent protectors (hereinafter referred to as "overcurrent protectors") with only AC power, rated voltage above 50V but not exceeding 440V, rated current not exceeding 32A, and maximum breaking current not exceeding 100A. Note 1: See Appendix A. Note 2: Mobile electrical accessories refer to electrical accessories composed of plugs and mobile sockets, such as mobile sockets defined in 3.4 of GB/T 2099.7-2015 and extension cord sockets defined in 3.12, wire extension components, etc. This standard specifies the inherent safety, functional safety, construction, operation, and parameter requirements of overcurrent protectors. This standard does not require or assess functions such as leakage protection, short circuit protection, surge protection, etc. This standard is not applicable to overcurrent protectors used in industrial engineering. This standard does not specify the response value for automatic disconnection that depends on the installation method of overcurrent protectors in the equipment. However, if these values have an impact on protecting users or the surrounding environment, the response values specified by the corresponding equipment standards or determined by the manufacturer shall apply in this standard
