High Energy Industrial Disc
CA Varistor Series
The CA Series of transient surge suppressors are industrial high-energy
disc varistors (MOVs) intended for special 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 of the same diameter may be stacked.
This series of industrial disc varistors are available in three diameter
sizes of 32, 40, and 60mm, with disc thicknesses ranging from 1.8mm
minimum to 32mm maximum. They offer a wide voltage range of from
250 to 2800 VM(AC)RMS .
For information on soldering considerations, refer to AN8820 update.
