Resistance

Ihold

=

Hold Current: maximum current device will sustain for 4 hours without tripping in 20°C still air.

Itrip

=

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

Vmax

=

Maximum voltage device can withstand without damage at rated current (Imax)

Imax

=

Maximum fault current device can withstand without damage at rated voltage (Vmax)

Pd

=

Power dissipated from device when in the tripped state at 20°C still air.

RIL

=

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

RAT

=

Maximum resistance of device at 20°C measured one hour after tripping.

CAUTION: Operation beyond the specified ratings may result in damage and possible arcing and flame.
