Note:
I
hold
= Hold current: maximum current device will pass without tripping in 20℃ still air.
I
trip
= Trip Current: minimum current at which the device will trip in 20℃ still air.
V
max
= Maximum voltage device can withstand without damage at rated current (Imax)
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℃ still air.
R
min
= Minimum resistance of device in initial (un-soldered) state.
R
1max
= Maximum resistance of device at 20℃ measured one hour after tripping or reflow soldering of 260℃ for 20 sec.
Caution
:Operation beyond the specified rating may result in damage and possible arcing and flame.
