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

V_M(AC)RMSvoltage 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.
