Varistor Products

Radial Lead Varistors > ZA Series

Description

The ZA Series of transient voltage surge suppressors

are radial leaded varistors (MOVs) designed for

use in the protection of low and medium-voltage

circuits and systems. Typical applications include

motor control, telecom, automotive systems,

solenoid, and power supply circuits to protect circuit

board components and maintain data integrity.

These devices are available in five model sizes:

5mm, 7mm, 10mm, 14mm and 20mm, and feature

a wide V
