Description
The DA and DB Series transient surge suppressors
are heavy-duty industrial Metal-Oxide Varistors
(MOVs) designed to provide surge protection for
motor controls and power supplies used in oil-
drilling, mining, and transportation equipment.
These UL recognized varistors have identical ratings
and specifications but differ in case construction
to provide flexibility in equipment designs.
DA Series devices feature rigid terminals to ensure
secure wire contacts. Both the DA and DB Series feature
improved creep and strike distance capability to minimize
breakdown along the package surface design that provides
complete electrical isolation of the disc subassembly.
See DA/DB Series Device Ratings and Specifications
table for part number and brand information.
