* Devices with hold current up to 1.5 amps are in development
I
H
=Hold current-maximum current at which the device will not trip at 23°C still air.
I
T
=Trip current-maximum current at which the device will always trip at 23°C still air.
V
MAX
=Maximum voltage device can withstand without damage at its rated current (I
MAX
).
I
MAX
=Maximum fault current device can withstand without damage at rated voltage (V
MAX
).
Pd=Typical power dissipated-type amount of power dissipated by the device when in the tripped state in 23°C still air environment.
R
MIN
=Minimum device resistance at 23°C prior to tripping.
R1
MAX
=Maximum device resistance at 23°C measured 1 hour post trip.
