Questions with PTC Resettable Fuses

  • Ask: How do PTC resettable fuses work?

    Answer: When overcurrent conditions occur, the Polymeric PTC material heats up and its resistance increase sharply. ... Upon fault current being removed, the resettable fuse cools and its resistance drops to the original extremely low value. The resettable fuse is \u201creset\u201d and allows the current through the circuit again.

  • Ask: How does a PTC fuse work?

    Answer: Both Polymeric (Positive Temperature Coefficient) PTC and traditional Fuse devices react to heat generated by the excessive current flow in a circuit. A fuse melts open, interrupting the current flow whereas a PTC limits current flow as it rises in temperature, changing from low to high resistance state.

  • Ask: What does PTC Fuse stand for?

    Answer: A resettable fuse (also known as a PTC) is a resistor that has very unique properties. ... The increased resistance (trip state) would break the circuit and allow only a small leakage current.

  • Ask: What is hold current resettable fuse?

    Answer: Hold current (IH), and Trip current (IT) of a resettable fuse are rated at 230C. Typically its trip current is twice as much as its hold current. The fuse will not trip at its hold current or blow and will trip at or above its trip current.
