Latest company news about Will the AOLITTEL PPTC device cycle? How does it stay latched?

AOLITTEL PPTC devices will not cycle between a normal and a tripped state when a fault condition is present. When the AOLITTEL PPTC device trips it goes from a low resistance to a high resistance state. In the high resistance state a small amount of trickle current is still present. This small trickle current is sufficient to maintain the AOLITTEL PPTC device in the high resistance state. The AOLITTEL PPTC device generally requires the power to the circuit to be interrupted, allowing the AOLITTEL PPTC device to cool before it will return to the normal low resistance state.
