Scope
Main technical content: This specification stipulates the performance requirements, test methods, and quality assessment procedures for metal oxide varistors (MOVs) with reliability indicators. These MOVs are installed in power supply, communication, and signal systems with AC voltages below 1000V (50/60Hz, RMS) or DC voltages below 1500V, used to protect equipment and personnel from high transient voltages and improve the immunity of protected equipment. This specification applies to metal oxide varistors, including thermal disconnector-protected metal oxide varistors (TDMOVs). It does not apply to assemblies consisting of metal oxide varistors and other overvoltage protection components.
