Varistor Products
High Energy Industrial
DA/DB Varistor Series
The DA and DB Series transient surge suppressors are heavy-duty
industrial metal-oxide varistors designed to provide surge protection for
motor controls and power supplies used in oil-drilling, mining, and trans-
portation 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 insure 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.
