Hold Current: maximum current device will sustain for 4 hours without tripping in 20°C still air.
Trip Current: minimum current at which the device will trip in 20°C still air.
Maximum voltage device can withstand without damage at rated current (Imax)
Maximum fault current device can withstand without damage at rated voltage (Vmax)
Power dissipated from device when in the tripped state at 20°C still air.
Minimum resistance of device in initial (un-soldered) state.
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.
