LR4-550RAF

PTC resettable fuses are regularly utilized in numerous mechanical applications due to their safety-related highlights. The LR4-550RAF application field is an example of a PTC resettable fuse, explicitly designed for industries, making it ideal for high-current applications. In a wide range of applications, these fuses not just provides protection for electrical implement and circuits, additionally help to support and extend product life expectancy.

A LR4-550RAF is a thermistor-based fuse which works depending on the solid state temperature-sensitive properties. This fuse has a current rating of 63A at 25°C and it can hold up to 73A at 65°C under specified conditions. It is made to work harmoniously with generally high-current applications, protecting wires and circuits from over-currents. It additionally gives protection from locked-rotor levels of beginning current in engines, ensuring that the circuits are not excessively released.

The advantage of PTC resettable fuses lies in their resetting ability after an over-current event. After the condition has been relieved, the internal PTC device of the fuse will switch back to its normal conducting state. This reduces the amount of time spent replacing fuses and requires less labor to maintain the electrical system. Last but not least, because the fuse does not require a conventional fuse, circuit programming can stay the same without having to rewire the entire system.

In conclusion, the LR4-550RAF fuse gives improved and reliable protection from over-voltage and over-current, which to some degree ensures that machines are less inclined to fail. There is no difference in internal or external wiring and no change in circuit programming needed when the fuse is changed, making this fuse perfect for applications where resistive loads need to be monitored. It offers a complete solution with superior protection that substantially reduces any downtime as a result of over-load conditions.
