Features
This product line is designed to provide protec-
tion against induced AC power current, direct
power contact and the natural lightning strike.
The HVR250 product line is widely used in the
? eld of telecommunications and network-
ing, ISDN and XSDN equipment. It also helps
equipment manufacturers pass ITU K20, K21 and
telcordia requirements.

* V int :Interrupt Voltage
** typcial value
V op : Operating Voltage(Vcd)
NOTE:
I hold = Hold current: maximum current device will pass without tripping in 20 °C still air.
I trip = Trip current: minimum current at which the device will trip in 20 °C still air.
I max = Maximum fault current device can withstand without damage at rated voltage (V max )
P d = Power dissipated from device when in the tripped state at 20 °C still air.
R min = Minimum resistance of device in initial (un-soldered) state.
R 1max = Maximum resistance of device at 20 °C measured one hour after tripping for 20 s.
Caution: Operation beyond the speci ? ed rating may result in damage and possible arcing and ? ame.
