hold

= Hold current: maximum current device will pass without tripping in 20°C still air.

trip

= Trip current: minimum current at which the device will trip in 20°C still air.

max

= Maximum voltage device can withstand without damage at rated current (I max)

max

= Maximum fault current device can withstand without damage at rated voltage (V

max

)

= Power dissipated from device when in the tripped state at 20°C still air.

min

= Minimum resistance of device in initial (un-soldered) state.

typ

= Typical resistance of device in initial (un-soldered) state.

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.
