PTC (positive temperature coefficient) resettable fuses are protective devices designed to protect electrical systems from short circuit and overload current. They are also known as polymeric positive temperature coefficient (PPTC) fuses or positive temperature coefficient (PTC) resettable fuses. PTC resettable fuses are current-limiting devices that are designed to open an internal switch when the current reaches a certain level, thereby cutting off power to the circuit when there is a fault. They are then designed to reset, allowing power to be restored to the circuit when the fault has cleared.

The RHE450 (or Resettable Fuse) is a type of PTC resettable fuse used to protect electrical circuits from overloads and short-circuits. It is designed to protect circuits and systems from dangerous voltage surges that may occur due to electrical fault conditions. It is used in a wide variety of applications, such as automotive, telecommunications, consumer electronics, and computer equipment. The RHE450 is designed to provide superior protection compared to other types of fuses.

The RHE450 has a unique design that utilizes a positive temperature coefficient material to sense the current level in the circuit. This material, when exposed to a current above a given threshold, will increase in resistance and consequently limit the current flowing through the circuit. This current-limiting action prevents the circuit from becoming damaged by over-current conditions.

The RHE450 is housed in a small, lightweight package that is ideal for portable applications. It has a wide range of operating temperatures (from -20°C to +85°C) and can handle up to 10 A with very fast response times (1-2mS). The device also features reverse current protection and an open-circuit trip level that is adjustable. The RHE450 is an effective solution for protecting low-voltage DC circuits from damage caused by transient faults.

The RHE450 is a versatile device that is used in a variety of applications. It is particularly well-suited for use in mobile and consumer electronics products, such as cell phones, MP3 players, and PDAs. The compact size makes it an ideal choice for use in these applications. It is also found in many computer applications where a rapid response time is required as well as in industrial control and safety systems.

The RHE450 is a reliable and cost-effective device that can provide effective protection for sensitive electrical systems and circuits. It is easy to install and requires minimal maintenance. Its wide temperature range and high current capacity makes it a suitable choice for many applications. It is also available in a wide range of sizes, allowing it to be used in smaller and larger circuits.
