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.
V

)
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 or reflow soldering of 260°C for 20 sec.
Caution: Operation beyond the specified rating may result in damage and possible arcing and flame.
