Varistor Products
NA Varistor Series
High Energy Industrial Square Disc
The NA Series of transient surge suppressors are varistors (MOVs) in
square disc form, intended for special industrial high-energy applications
requiring unique electrical contact or packaging methods provided by the
customer. The electrode finish of these devices is solderable and can
also be used with pressure contacts. Discs may also be stacked.
The NA Series varistor is a square 34mm device, with thicknesses
ranging from 1.7mm minimum for the 250V device to 7.5mm maximum
for the 750V device. For information on mounting considerations refer to
Application Note AN8820.
This disc is also available with encapsulation and PCB leads. See
Littelfuse HB34 Sales.
