●

Ih=Hold current: maximum current at which the device will not trip at 25 still air .

●

It =Trip current minimum current at which the device will always trip at 25℃ still air .

●

Vmax=Maximum voltage device can withstand without damage at rated current.

●

Imax=Maximum fault current device can withstand without damage at rated voltage.

●

Ttrip=Maximum time to trip at 5 times hold current

●

Rmax=Maximum device resistance at 25 prior to tripping.

●

Rmin=Minimum device resistance at 25 prior to tripping.
