Varistor Products 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. “Recommendations for Soldering Terminal Leads to MOV Varistor Discs”.
