The KA 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.
