适用范围

This Recommendation:gives the characteristics ofmetaloxide varistors (MOVs)used in accordance with [b-ITU-T K.11] for the protection of power supply circuits and signal circuits of telecommunication installations against overvoltages; does not deal with combinations of several MOVsconnected in series and/or in parallel, nor combinations of MOV with other components; does not deal with mountings and their effect on MOV characteristics, the characteristics apply to MOV as a component, mounted only in the ways described for the tests; does not deal with mechanical dimensions; does not deal with quality assurance requirements.
