PTC Resettable Fuses

PTC Resettable Fuses are a form of protection designed to protect a circuit from overloads and short circuits. Unlike traditional fuses, they reset themselves after they have tripped. The PTR060V0090-TR is one such example of a PTC Resettable Fuses that is designed to provide reliable protection of circuits up to 600V.

Applications

The PTR060V0090-TR is suitable for a wide range of applications, ranging from motor control circuits, to protection of electronic components in consumer electronics. It is most commonly used in applications where a wide range of circuit voltages is present, up to 600V.

Design and Working Principle

The PTR060V0090-TR consists of a PTC element, a differential circuit, and an internal relay. The PTC element is a Positive Temperature Coefficient (PTC) thermistor, which is a resistive element that increases gradually in resistance as the temperature increases. This allows the PTR060V0090-TR to provide overload and short circuit protection as the current increases and the temperature rises.The differential circuit is connected in parallel with the main circuit and reacts to any abnormal current increase. When this current increase exceeds the pre-set value, the internal relay will trip and disconnect the circuit. This will prevent any further current from flowing and protect the circuit from overloads and short circuits. After the fault has been cleared, the PTC element will gradually cool and reset, allowing the circuit to continue functioning as normal.

Conclusion

The PTR060V0090-TR is a versatile and reliable PTC Resettable Fuse, offering circuit protection up to 600V. With its advanced features and protective design, it is ideal for a wide range of applications, ranging from motor control to consumer electronics. With its ability to reset itself after faults, it is an ideal choice for anyone looking for effective circuit protection.
