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.
