Components for low-voltage surge protective devices Part 331: Specification for metal oxide varistors (MOV) - IEC 61643-331:2003
出版:International Electrotechnical Committee

专家解读视频
IEC 61643-331:2003 details the test specifications for metal oxide varistors (MOV), which are used for applications up to 1000 V a.c. or 1500 V d.c. in power line, or telecommunication, or signalling circuits. The MOVs are designed to protect apparatus or personnel, or both from high transient voltages. Does not deal with hybrid devices. Does not apply also to mountings and their effect on the MOVs characteristics.
