PTC Resettable Fuses (“PolySwitch”) are very useful components in a variety of applications. RXE110-1 is one of the most common PTC Resettable Fuses available on today’s market. This article will discuss the application field and working principle of RXE110-1.

Application Field

RXE110-1 is mainly used in circuit protection applications. It can be used in AC/DC switching power supplies, consumer electronics, audio/visual equipment, and general consumer appliances. It is particularly well-suited for applications that require fast and reliable resettable circuit protection.

RXE110-1 is also used in surge suppression and load disconnect applications. This makes it ideal for use in automotive, medical and industrial environments. Because of its small size, it is also suitable for use in compact applications where space may be at a premium.

Working Principle

RXE110-1 is a thermally operated PTC device. It consists of two parts: a base and a switch. The base is made up of a thermally conductive material and the switch is made up of a bimetal strip. When the device is subject to an overcurrent, the bimetal strip begins to heat up. This heat is then transferred to the base, which in turn causes a thermal expansion of the base material. This thermal expansion leads to the switch contacts opening, thus disconnecting the circuit.

Once the overcurrent is removed, the device will gradually cool down and the switch contacts will close again. This allows the device to reset and the circuit to be reconnected. This process is highly dependable and is a major benefit of using RXE110-1.

Conclusion

RXE110-1 is an invaluable solution for applications that require reliable and fast resettable circuit protection. Its ability to disconnect and reset quickly make it ideal for automotive, medical and industrial settings. Its small size also makes it suitable for use in space constrained conditions. The working principle behind RXE110-1 makes it even more successful as it has proven itself to be highly reliable.
