Description
The LA 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 Series varistors are available in four model
sizes: 7mm, 10mm, 14mm and 20mm; and have a
V
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.
