LA Varistor Series
The LA Series of transient voltage surge suppressors are radial-lead
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 Series varistors are available in four model sizes: 7mm, 10mm,
14mm and 20mm; and have a VM(AC)RMS voltage range from 130V
to 1000V, and an energy absorption capability up to 360J. Some LA
series model numbers are available with clamping voltage selections,
designated by a model number suffix of either A or B. The Aselection is
the standard model; the Bselection provides a lower clamping voltage.
See LA Series Device Ratings and Specifications table for part number
and brand information.
