NOTE:
I hold =
I trip =
Vmax =
I max =
Hold current: maximum current device will pass 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 (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 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 specified rating may result in damage and possible arcing and flame.
