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

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

I _max= Maximum fault current device can withstand without damage at rated voltage (V_max

)

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.

*Note: Some devices in this product series may have “–C“ in the Part Number. The “–C“ should be omitted when placing orders for the device.
