ZA Varistor 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 VDC voltage range of 5.5V to 615V.
See ZA Series Device Ratings and Specifications
Table for part number and brand information.
