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

I _trip= Trip current: minimum current at which the device will always at 25℃ still air.

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

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

T _trip=Maximum time to trip(s) at assigned current.

P_dtyp.= Typical power dissipation: typical amount of power dissipated by the device when in state air environment.

R _min= Minimum device resistance at 25℃ prior to tripping.

R_1max= Maximum resistance of device at 25℃ measured one hour after tripping.

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