IT : Trip current: minimum current that will switch the device from low-resistance to high-resistance in 20°C still air unless otherwise specified. VMAX : Maximum voltage device can withstand without damage at rated current. IMAX : Maximum fault current device can withstand without damage at rated voltage. PD : Power dissipated from device when in the tripped state in 20°C still air unless otherwise specified. RMIN : Minimum resistance of device as supplied at 20°C unless otherwise specified. RMAX : Maximum resistance of device as supplied at 20°C unless otherwise specified. R1MAX : Maximum resistance, measured at 20°C unless otherwise specified, of device one hour after being tripped the first time.
