AbolishedComponents for low-voltage surge protective devices - Part 331: Secification for metal oxide varistors(MOV)
低压电涌保护器元件 第331部分：金属氧化物压敏电阻（MOV）规范
Application Summary AI generated
This standard specifies the performance requirements, test methods, and classification for metal oxide varistors (MOVs) used as key components in low-voltage surge protective devices (SPDs). It is applied in electrical engineering contexts, particularly for manufacturing, quality assurance, and procurement of MOVs in power distribution systems, telecommunications, and electronic equipment protection. The standard ensures MOVs meet safety and reliability criteria for suppressing transient overvoltages in residential, commercial, and industrial installations.
