PTC Resettable Fuses are a recently-developed form of over-current protection devices. They are increasingly becoming popular due to their capabilities for providing versatile protection against rising currents in a variety of applications. RXEF135-AP is a particular type of PTC resettable fuse that has been designed specifically for applications involving medium-high power switching. By providing an effective method of reducing risk associated with current risk, this type of fuse is often used in industries where reliable protection against sudden rises in current is paramount.

The RXEF135-AP resettable fuse can provide a current ranging from 1.0A to 135A. It has a voltage rating of 30-60V and is generally used in a range of applications including consumer electronics, transportation, medical instruments, industrial automation and communication. It has been designed to provide superior performance and extremely reliable protection, even when exposed to shock, vibration, temperature variation and other harsh environmental conditions. Its overall design is intended to reduce the maintenance costs associated with traditional thermal fuses due its non-destructive method of resetting.

The working principle of the RXEF135-AP resettable fuse consists of a positive temperature coefficient (PTC) resistor placed in parallel with a current sensing resistor. When a current >= the current rating of the fuse flows through the parallel network, the PTC will heat up, leading to its resistance increasing. This will then limit the current passing through the circuit, and as such protect the electronic device from any potential damage. The design of the RXEF135-AP allows the current to be reduced to an acceptable level while preserving the integrity of the system components.

To reset the RXEF135-AP resettable fuse, the current must be brought to below the trip level. This will cause the PTC resistor to cool down, and return to a lower resistance level. At this point, the circuit will be able to operate as it did prior to the event, without any further losses of power or components. It should be noted that the rate of self-resetting of the fuse may vary depending on the temperature of the surroundings, as the unit must be cooled back down to the ambient temperature before it is reset.

In terms of applications, the RXEF135-AP resettable fuse can be used in a variety of commercial and industrial settings. This includes automated machines, industrial process control systems, automotive electronics, consumer electronics applications and more. Moreover, due to its non-destructive resetting feature, it can be used in situations where regular monitoring and resetting of the circuit is required. This makes it especially suitable for applications involving frequent current surges, such as those found in medical instrumentation.

The RXEF135-AP resettable fuse offers a reliable and cost-effective method of current protection in a variety of situations. This is due to the combination of its low voltage rating, high current rating, and non-destructive resetting capability. Its design ensures that the electronic system is efficiently protected from the damaging effects of over-currents, while it can be easily reset if the issue arises. Therefore, it is an ideal choice for a wide range of applications, especially those that require frequent monitoring and periodic resetting.
