PTC Resettable Fuses presently exist in a wide variety of products and cater to a broad section of industries with low-resistance devices designed in order to protect against electric surges. The RUEF250 application field consists of applications that require a high current rating and irregular current surges. This type of PTC fuse protects against overheating, fires, and electric shock to maintain the health and safety of its users.

The design of the RUEF250 consists of a thermally sensitized polymeric body, which acts to break the circuit in case of an electric overcurrent. The device is triggered when the current flow exceeds the rating, thereby activating the protection mechanism. It is designed to allow for quick disconnection of the electrical network from the mains in case of any surge.

RUEF250 also includes an indication system, which gives users a visual or audible indication when the fuse is activated. The indication system allows the users to quickly identify the fuse state and take corrective measures accordingly.

The working principle of the RUEF250 is based on the concept of a self-resetting thermal cut-off fuse. The body of the device contains a thermally sensitive PTC material, which functions as a temperature sensing element. When the current flow exceeds the rated current, the PTC material heats up and activates the thermal cut-off fuse. Once the rated current is exceeded, the PTC material cools down and re-establishes the circuit.

This device is designed with a fail-safe mechanism that eliminates the possibility of electric shock due to incorrect wiring or loose connections. The device is also designed to protect against thermal runaway, which occurs when a surge in current results in an uncontrolled rise in the device temperature. Thus, it provides reliable protection against overloads, short circuits, and electrical surges.

The RUEF250 is widely used in a wide range of applications such as automotive, manufacturing, computer, communications and networking, medical electronics, consumer electronics, and aerospace. It is designed with a wide range of current ratings and is available in various sizes. This device is designed for easy installation and it is also available with optional accessories such as mounting brackets and grounding bars.

To sum up, RUEF250 is a Polymeric Positive Temperature Coefficient Resettable fuse and is designed to protect against electric shocks, overheating, fires, and electric surges. The device is designed with a self-resetting mechanism and comes with various current ratings and mounting brackets for easy installation. The indication system allows users to quickly identify the state of the fuse, thereby helping to take corrective measures in case of a surge.
