POLYFUSE(R) RESETTABLE FUSES
VLD
Strap Type, 12 V
Standard
UL 1434 1st Edition CSA C22.2 No. 0 CSA TIL No. CA-3A cULus Recognition TUV The new VLD product series feature a slim, low profile and low resistance design. These devices are ideal to install directly onto the latest generation batteries including cylindrical and prismatic cells. The VLD product offers protection against both overcurrent and overtemperature fault conditions.

NOTE: I hold = I trip = Vmax = I max =
Hold current: maximum current device will pass without tripping in 25 C still air. Trip current: minimum current at which the device will trip in 25 C still air. Maximum voltage device can withstand without damage at rated current (I max) Maximum fault current device can withstand without damage at rated voltage (Vmax)
Pd = Power dissipated from device when in the tripped state at 25 C still air. R min= Minimum resistance of device in initial (un-soldered) state. R 1max= Maximum resistance of device at 25 C measured one hour after tripping for 20 s. Caution: Operation beyond the specified rating may result in damage and possible arcing and flame.
