T/CEEIA 388-2019 Over-voltage and Under-voltage Protection Device Technical Specification
Basic Information
Scope
Scope: This standard applies to over-voltage and under-voltage protectors (hereinafter referred to as OUPDs) used in household and similar applications, with an AC rated frequency of 50Hz, a rated voltage not exceeding 400V (relative to the neutral line voltage of 230V), and a rated current not exceeding 125A. This standard specifies the terms and definitions, classification, characteristics, marking and other product information, standard working conditions for use and installation, structural and operational requirements, and testing of OUPDs. Note: The installation and use procedures for OUPDs are specified in JGJ 242-2011. OUPDs are intended for use in environments with a pollution level of 2.
