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.
