The new VTD product series feature a slim, low
profile and low resistance design. These devices
are ideal to be installed directly onto the latest
generation batteries including cylindrical and
prismatic cells. The VTD product offers protec-
tion against both overcurrent and overtempera-
ture fault conditions.
