Axial Leaded – 1kA > AK1 series
The AK1 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.
