Metal-Oxide Varistors (MOVs) Radial Lead Varistors > LA Varistor Series RoHS LA Varistor Series Description The LA Varistor Series of transient voltage surge suppressors are radial leaded varistors (MOVs) that are designed to be operated continuously across AC power lines. These UL recognized varistors require very little mounting space, and are offered in various standard lead form options. The LA Varistor Series are available in four model sizes: 7mm, 10mm, 14mm and 20mm and have a V voltage range from 130V to 1000V, and an M(AC)RMS energy absorption capability up to 360J. Some LA Series model numbers are available with clamping voltage selections, designated by a model number suffix of Agency Approvals either A or B. The A selection is the standard model the B selection provides a lower clamping voltage.
