A PTC resettable fuse, often referred to as a polyfuse, is an electrical device used to protect from overcurrent conditions. They are a type of thermal fuse, which means that they are self-resetting, unlike traditional fuses that must be replaced after an overload. PTC resettable fuses are designed to protect against unintentional or accidental short circuits in wiring, as well as against overloading of power supplies.

The RHE 1000 is a resettable fuse with a reset voltage of 10V and a holding voltage of 6V. It can be used in a variety of applications such as audio/video, clocks, computers, communication equipment, consumer electronics, and automotive applications. The reset voltage of 10V is ideal for applications requiring a low reset voltage with a current rating of 1A.

The working principle of the RHE 1000 is based on a thermistor which is a device that has a negative temperature coefficient of resistance, meaning that the resistance of the thermistor decreases with increasing temperature. This characteristic is then used in a PTC resettable fuse to protect equipment from overcurrent conditions. When the device is under normal operating conditions, the thermistor maintains a low resistance allowing the current to flow freely. However, when an overcurrent condition is present, the thermistor will heat up causing the resistance to increase and the current will then be limited, and eventually shut off.

This type of fuse is ideal for use in areas where frequent changes in current levels can occur, such as in audio/video equipment, or even in automotive applications. They are also easy to use, simply requiring the user to plug the device into the power source and it will remain in a low-resistance state, until an overcurrent condition occurs. Once the overcurrent is removed, the PTC resettable fuse will cool and reset back to its low resistance level.

The RHE 1000 PTC resettable fuse is not only easy to install and maintain, but is also an effective way to protect devices from overcurrent conditions. It offers a wide range of current ratings and reset voltages, and is a great alternative to traditional fuses for applications requiring frequent changes in current levels. With its easy reset feature and increased safety, the RHE 1000 PTC resettable fuse makes an excellent choice for a wide variety of applications.
