Radial Lead Transient Voltage Suppressors (TVS)
KC Series
Description
The KC 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.
