PTC Resettable Fuses are current-sensitive, polymeric devices that can be reset after their rated currents have been exceeded. The RXEF040S-2 is a cost-effective, UL-certified radial-lead PCB fuse. It is designed for use in instrumentation, digital LED lighting applications, telecommunications systems, and many other electronic circuits.

The RXEF040S-2 operates on a bi-metallic mechanism. This mechanism stops the flow of current when it surpasses the rated value. The device is self-resetting and safe to use once the problem has been fixed or the faulting circuit is turned off. Benefits of this design include cost savings due to not needing to purchase new fuses, and less repair time due to the self-resetting nature of the bin-metallic mechanism.

The RXEF040S-2 can be used in a wide variety of applications due to its high wattage rating and low switching current. This device offers a maximum wattage rating of 25W and an optimal switching current range of 0.1A to 1.2A. It can be used as a secondary fuse in a series string of low wattage LED fixtures, such as those used in landscape lighting. The RXEF040S-2 can be used in telecommunications systems to protect network delicators from overloads and short-circuits. It can also be used in consumer electronic applications as an over-current protection device.

The RXEF040S-2 is a great choice for many applications due to its unique bi-metallic design and low-cost. Its self-resetting feature makes it very convenient, as it eliminates the need to constantly replace blown fuses. This device has a wide range of wattage ratings and current switches, requiring less customization for specific applications. This makes it an ideal choice for both commercial and consumer applications.
