IH=Hold current-maximum current at which the device will not trip at 23ºC still air.
IT=Trip current-minimum current at which the device will always trip at 23ºC still air.
VMAX=Maximum voltage device can withstand without damage at its rated current.
I MAX= Maximum fault current device can withstand without damage at rated voltage (VMAX).
Pd=Maximum power dissipated from device when in tripped state in 23ºC still air environment.
RMIN=Minimum device resistance at 23ºC.
R1MAX=Maximum device resistance at 23ºC, 1 hour after tripping.
Physical specifications:
Lead material: 0.1mm nominal thickness, quarter-hard nickel.
Insulating material: Polyester tape
