I trip = Trip current: minimum current at which the device will trip in 20C still air. V max = Maximum voltage device can withstand without damage at rated current (I max ) I max = Maximum fault current device can withstand without damage at rated voltage (V max ) P d = Power dissipated from device when in the tripped state at 20C still air. R min = Minimum resistance of device in initial (un-soldered) state. R 1max = Maximum resistance of device at 20C measured one hour after tripping. Caution: Operation beyond the specified rating may result in damage and possible arcing and flame. Agency Approvals * Effective January 1, 2010, all 30R PTC products will be manufactured Halogen Free (HF). Existing Non-Halogen Free 30R PTC products may continue to be sold, until supplies are depleted.
