I hold = Hold current: maximum current device will pass without tripping in 23°C still air. I trip = Trip current: minimum current at which the device will trip in 23°C still air. 

- Vint = Maximum voltage the device can withstand without damage at rated current (I max) Vop=  The device regular operation voltage 

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

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

   - R max = Maximum resistance of device in initial (un-soldered) state. 

   - R 1max =  Maximum resistance of device at 20°C measured one hour after tripping. 

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

- P d = Power dissipated from device when in the tripped state at 23°C still air.
