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.

NOTE:

I

Hold current: maximum current device will pass without tripping in 25 °C still air.

I

Trip current: minimum current at which the device will trip in 25 °C still air.

V

Maximum voltage device can withstand without damage at rated current (I

I

Maximum fault current device can withstand without damage at rated voltage (V

P

Power dissipated from device when in the tripped state at 25 °C still air.

R

Minimum resistance of device in initial (un-soldered) state.

R

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.
