PTC Resettable Fuses are widely used to protect electronics devices and components from damage due to excessive current. The RUEF250-2 Application Field and Working Principle provide maximum protection from damaging overcurrent faults that can otherwise damage electronic devices and components.

The RUEF250-2 is a 7.5A, 250V PTC Resettable Fuse that provides reliable and cost-effective protection to wired and wireless telecommunications/networking systems from critical overcurrent faults that may otherwise result in device or system damage. The RUEF250-2 includes a thermal, electro-mechanical bimetallic construction. This PTC resettable fuse features an operating voltage of 250V and a rated current of 7.5A.

The RUEF250-2 is composed of two basic elements that work together to provide protection: the thermal element and the electro-mechanical element. The thermal element is responsible for responding to an increase in temperature, whereas the electro-mechanical element serves to ensure a reliable resetting response to any overcurrent condition. The thermal element is activated when it reaches a temperature of 11°C (52°F). At that point, it rapidly moves a contact arm up to break any excessive voltage that may be present. In the case of overcurrent flow, this same thermal element restrains a bimetallic plate, which eventually reaches a temperature high enough to cause the electro-mechanical element to move. This movement will trip the system, disconnecting the relevant devices and components.

Due to the RUEF250-2\'s small size and easy operation, it is widely available in the majority of standard situations. Each RUEF250-2 unit is capable of reliably supplying the rated load at 250V and 7.5A. It is also able to withstand an overcurrent of 7.5A-10A, enabling it to re-establish the original circuit connection after the overcurrent fault has been rectified. In addition, the fuse provides complete isolation from the load terminals during tripping operations, ensuring a safe operation.

The RUEF250-2 application field and working principle enhance its usefulness and reliability with industrial, commercial, medical and a wide variety of other applications. The advanced PTC technology used in the design of the RUEF250-2 provides superior overcurrent protection for your applications. It enables both current and temperature limitation, together with a reliable resetting response, effectively protecting the units during overcurrent faults.

In conclusion, the RUEF250-2 Application Field and Working Principle is essential for effective overcurrent protection. Its reliable operation and quality construction make the RUEF250-2 an ideal choice for high-end electronics. Its simple design allows for easy installation, which increases its application flexibility. In addition, PTC resettable fuses offer complete isolation from the load terminals during tripping operations, allowing for a safe operation. Therefore, the RUEF250-2 is an optimal choice for providing reliable and cost-effective overcurrent protection.
