Data Sheet
Radial Lead Metal-Oxide Varistors for Line
Voltage Operation
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
“A” selection is the standard model; the “B” selection
provides a lower clamping voltage.
See LA Series Device Ratings and Specifications table for
part number and brand information.
