PTC Resettable Fuses, or Polymeric Positive Temperature Coefficient Fuses, are among the most trusted passive components used in a wide variety of markets and electrical applications. They are known for their reliability and versatility, as they are able to protect electrical circuits against overcurrents, surges, and electrical short circuits. The most common size for these devices is the RUE600, though there are also larger and smaller sizes available. This article will explore the application field and working principle of the RUE600 PTC Resettable Fuse.

The PTC Resettable Fuse is primarily used as overcurrent protection for all types of electronic equipment. These devices can be used for a variety of different applications, including mobile and stationary devices, such as computers, routers, cameras, telephones, and many other modern electronics. In addition, they can be used for the protection of wires or cables as well as replacing traditional fuses in a variety of circuits.

The RUE600 PTC Resettable Fuse is typically used in applications where substantial current overcurrent protection is needed. It has a wide operating temperature range and is designed to offer reliable protection up to 600V and up to 25 A in DC applications. The device is rated at 300V and up to 10A for AC applications. The fuse has an auxiliary contact that transmits a signal when the fuse is tripped, allowing for remote monitoring and detection of a failure. The operating time of these devices typically ranges from 500ms to 5s and the operating temperature range is -40℃ ~ 125℃.

The working principle of a PTC Resettable Fuse is based on the positive temperature coefficient of the active elements within the fuse. This fuse element is composed of a mixture of non-metallic and metallurgic materials, such as polyacetal and palladium or nickel. As long as the current going through the device is below its rated protection limit, it will remain in an unstressed mode, with an open connection. When the current going through the device surpasses its rated current, however, the fuse will go into a stressed mode and the contact will be interrupted, protecting the circuit.

Upon achieving stability, the fuse element of the PTC Resettable Fuse will gradually recover into its original unstressed mode. This process begins slowly and gradually increases until it returns to normal operating conditions. These devices are designed to protect the circuit until the problem that caused the fuse to trip can be resolved. Once the problem is resolved, the device can be reset and put back to normal operation.

In summary, RUE600 PTC Resettable Fuses are reliable and versatile components that are widely used in a variety of markets and electrical applications. They are designed to provide overcurrent protection for electronic equipment and ensure protection of many types of wires and cables. Their working principle is based on the positive temperature coefficient of the active elements within the fuse, which allows them to open the connection when an overcurrent is detected. These devices are designed to automatically reset after the issue that caused the fuse to trip has been resolved, allowing for normal operation.
