Radial Lead Varistors > ZA Series
ZA Varistor Series
Description
RoHS
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, 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
DC
voltage range of 5.5V to 615V.
