Varistor Products
Base Mount
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 VM(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.
