Metal-Oxide Varistors (MOVs)Radial Lead Varistors LA Varistor SeriesLA Varistor SeriesRoHSDescriptionThe LA Varistor Series of transient voltage surgesuppressors are radial leaded varistors (MOVs)that are designed to be operated continuouslyacross AC power lines. These UL recognizedvaristors require very little mounting space, and areoffered in various standard lead form options.Agency ApprovalAgency FileNumberUL1449E320116The LA Varistor Series are available in four modelsizes: 7mm, 10mm, 14mm and 20mm; and have aVM(AC)RMS voltage range from 130V to 1000V, and anenergy absorption capability up to 360J. Some LA Seriesmodel numbers are available with clamping voltageselections, designated by a model number suffix ofeither A or B. The 'A' selection is the standard model;the 'B' selection provides a lower clamping voltage.See LA Series Device Ratings and SpecificationsTable for part number and brand information.116895FeaturesAgency ApprovalsAgencyCECC 42201-006IEC 61051-1IEC 61051-2IEC 60950-1 (Annex Q) for 14mm and 20mm onlyCECC 42201-006IEC 61051-1IEC 61051-2IEC 60950-1 (Annex Q) for 14mm and 20mm onlyE1273/FAdditional InformationDatasheetResources Lead–free, HalogenFree and RoHScompliant.
