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  
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.
