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.
