Line Voltage Operation, Radial Lead

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 V

M(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.

Features

• Energy Absorption Capability (W

) ....................Up to 360J

• Wide Operating Voltage Range

M(AC)RMS

.....................................130V to 1000V
