The KB Series of high current transient suppressors have been

specially designed for use in A.C. line protection and any demanding

applications (AC or DC). Any voltage rise due to increased current

conduction is contained to a minimum, providing the best possible

protection level. They can also be connected in series and/or parallel

to create very high capacity protection solutions.
