Features
The new VLD product series feature a slim, low
profile and low resistance design. These devices
are ideal to install directly onto the latest genera-
tion batteries including cylindrical and prismatic
cells. The VLD product offers protection against
both overcurrent and overtemperature fault
conditions.
