PTC Resettable Fuses have rapidly gained acceptance as the preferred means of providing overcurrent protection. The PFRA.400 is a Resettable Fuse that can provide reliable circuit protection in applications where an overcurrent condition is essential.

The fully self-resetting PFRA.400 Resettable Fuse provides a cutting-edge form of circuit protection. By averting potential damage to delicate circuits, the PFRA.400 reduces product liability and increases customer satisfaction. Specifically, the fuse eliminates the nuisance of common fuse replacement and provides valuable time savings in existing and under-development lines.

A Resettable Fuse consists of a thermally sensitive PTC element encapsulated in ceramic. The fuse operates by "tripping" when a predetermined current is exceeded. The thermal trip current is programmable, and PTC Resettables such as the PFRA.400 are certified to UL61439 standards and UL60898 standards.

The PTC Resettable Fuses combine the capability to handle high fault currents with accurate, repeatable overcurrent protection. They are often chosen for their low thermal resistance and for the wide temperature range of operation, which allow trouble-free operation over a wide range of ambient conditions.

The PFRA.400 Resettable Fuse can be used in a variety of consumer and industrial applications. It is particularly suited for use in appliances, instrumentation, computers, LED lighting, low voltage motors, and solar applications. It can also be used as an alternative to conventional fuses in high current power supplies or other applications that frequently experience high fault currents.

The PFRA.400 Resettable Fuse provides a wide range of features, such as a wide operating temperature range, high fault current capacity, and high overcurrent protection accuracy. It also has superior reliability due to its high fatigue life, making it ideal for applications with extended operational life requirements.

The PFRA.400 Resettable Fuse is also easy to install, and the automatic resetting feature eliminates the need for regular service or replacement. The fuse is designed to reset itself after the fault current is removed. This enables it to reset in a matter of a few seconds, making it the ideal choice for applications requiring frequent resetting capabilities.

In summary, the PFRA.400 Resettable Fuse is a reliable and cost-effective protection solution suitable for a variety of applications. Its high current handling capacity, wide operating temperature range, and low thermal resistance feature makes it an ideal choice for consumer and industrial applications requiring reliable overcurrent protection.
