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

Caution: Operation beyond the specified rating may result in damage and possible arcing and flame.

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

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

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.

R | Maximum resistance of device at 20°C measured one hour after tripping or reflow soldering of 260°C for 20 sec.

¹ Some older references to these devices may include "-C" in the Part Number. The "-C" should be omitted when placing new orders for the device.
