Permissible continuous operating current is ≤ 100% at ambient temperature of 20ºC (68ºF).
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.
Vmax = Maximum voltage device can withstand without damage at rated current (I max)
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 specifi ed rating may result in damage and possible arcing and fl ame.
