Ih = Hold current-maximum current at which the device will not trip at 23°C still air. 

It = Trip current-minimum current at which the device will always trip at 23°C still air. 

Vmax = Maximum voltage device can withstand without damage at its rated current. 

Imax = Maximum fault current device can withstand without damage at rated voltage (V maximum). 

Pd = Typical power dissipated from device when in the tripped state in 23°C still air environment. 

RMin = Minimum device resistance at 23°C. 

R1Max = Maximum device resistance at 23°C, 1 hour after tripping. 

## **Physical specifications:** 

Lead material : Tin plated copper. Soldering characteristics :  Solder ability per ANSI/J-STD 002 Solder heat withstand per IEC 68-2-20. Insulating coating : Flame retardant epoxy polymer.
