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: 0.13mm nominal thickness, quarter-hard nickel.

Insulating material: Polyester tape
