PTC Resettable Fuses are a popular type of loads commonly used in industrial and residential applications. They provide protection to against any over-current or over-voltage event, ensuring that downstream loads are not damaged by high current or voltage levels. The RUE800 is a type of resettable fuse with a wide range of applications. This article will provide an overview of its application field and working principle.

RUE800 Application Field

The RUE800 is a rugged, reliable, and affordable resettable fuse used in many applications. This type of fuse is especially popular for use in DC power systems in harsh environments, as it provides system protection against voltage and current transients. It is also suitable for use in automotive, industrial, medical, residential, and trailer applications.

Industrial Applications

The RUE800 is an ideal choice for industrial applications, as it can provide robust protection against voltage and current spikes. It is well suited for use in heavy-duty off-road applications, including mining, agricultural, construction, and defence equipment, where it provides valuable protection against electrical impulses from the battery or engine. The RUE800 can also be used in high-voltage applications, such as AC or DC industrial control systems, and is especially suited for use in energy storage systems, as it can help ensure system protection against over-voltages and over-currents.

Residential Applications

In residential applications, the RUE800 can be used to protect systems from overloads, making sure that downstream loads do not malfunction or cause system damage. The resettable fuse is also well suited for use as an effective surge protection device, particularly in cases where system power is exposed to lightning or other sources of high-voltage surges. Moreover, these fuses are suitable for use in areas prone to systematic voltage fluctuations such as power grids or metropolitan networks, providing added protection by cutting the power supply if a surge is detected.

RUE800 Working Principle

The RUE800 is made of a polymeric PTC (positive temperature coefficient) resistor, a negative temperature coefficient resistor, and a switch. This combination of components works together to provide protection against over-currents and over-voltages. The PTC resistor is able to sense small increases in current or voltage levels, causing it to increase in temperature. This heat is then transferred to the negative temperature coefficient resistor, causing it to increase in resistance, which in turn causes the switch to disconnect the current flow. This process takes place within seconds and prevents downstream loads from being damaged. After the overload has cleared, the temperature of the negative temperature coefficient resistor cools, lowering its resistance. The switch then reconnects the current flow, allowing the application to restart.

In conclusion, the RUE800 is a resettable fuse well suited for a wide range of applications. Its combination of a PTC resistor, a negative temperature coefficient resistor, and a switch makes it ideal for use in DC power systems in harsh environments. It is also suitable for use in automotive, industrial, medical, residential, and trailer applications, providing added protection against overloads and voltage surges. It is an affordable and reliable solution for ensuring optimal protection in any application.
