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