I trip = Trip current: minimum current at which the device will trip in 23°C still air. V max = Maximum voltage device can withstand without damage at rated current (Imax) I max = Maximum fault current device can withstand without damage at rated voltage (Vmax) Pd = Power dissipated from device when in the tripped state at 23°C still air. R min = Minimum resistance of device in initial (un-soldered) state. R 1max = Maximum resistance of device at 23°C measured one hour after tripping. Caution: Operation beyond the specified rating may result in damage and possible arcing and flame. Agency Approvals AGENCY AGENCY FILE NUMBER E183209 R501 19318 * Effective January 1, 2010, all 16R PTC products will be manufactured Halogen Free (HF).
