Varistor Products

PA Varistor Series

The PA Series of transient surge suppressors are metal-oxide varistors

(MOVs) featuring a rigid base mount package construction, and are

useful in applications which are subject to vibration.

These UL and CSA recognized varistors are available in a wide range of

operating voltages, from 130V to 660V V M(AC)RMS . The base-mount

package has a quick-connect tab terminal that provides a fast, secure

lead attach. The mounting base forms the second electrical connection,

usually chassis ground. Meeting rigid NEMA standards, PA series

varistors have a creep and strike distance capability that minimizes

breakdown along the package surface.

See PA Series Device Ratings and Specifications table for part number

and brand information.
