B
“resettable fuses” are used in a wide variety of
circuit protection applications.
Under fault conditions the device resistance
will rise exponentially and remain in a
“tripped” state, providing continuous circuit
protection until the fault is removed. Once the
fault is removed and the power cycled, the
device will return to its normal low resistance
state.
