Resistance
Ihold
=
Hold Current: maximum current device will sustain for 4 hours without tripping in 20°C still air.
Itrip
=
Trip Current: minimum current at which the device will trip in 20°C still air.
Vmax
=
Maximum voltage device can withstand without damage at rated current (Imax)
Imax
=
Maximum fault current device can withstand without damage at rated voltage (Vmax)
Pd
=
Power dissipated from device when in the tripped state at 20°C still air.
RIL
=
Minimum resistance of device in initial (un-soldered) state.
RAT
=
Maximum resistance of device at 20°C measured one hour after tripping.
CAUTION: Operation beyond the specified ratings may result in damage and possible arcing and flame.
