LA Varistor Series
Description
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)
voltage range from 130V to 1000V, and an energy
RMS
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.
