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

I_max= Maximum fault current device can withstand without damage at rated voltage (V_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.
