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.
