PTC Resettable Fuses are electrical components that serve as a safety device for protecting connective wiring and circuitry from overheating or power surges. The RLDP800UFF application field and working principle is one example of a resettable fuse technology. This RLDP800UFF PTC Resettable Fuse is a high-accuracy protective device designed for use in autotransformer, battery charging, DC-DC conversion, smart meter and other electrical applications. It offers accurate over-current protection and auto-reset protection. All RLDP800UFF series fuses feature triacs as the base element, which allows for current flow in both directions when conducting.The RLDP800UFF Resettable Fuse works by sensing a current overload that has reached a predetermined level. When this happens, the two triac elements inside the fuse will start to heat up, at which point the two contacts between the two elements will break. This causes the current to be cut off and prevent further damage or overheating of the circuit components.The RLDP800UFF Resettable Fuse also features a low thermal impedance design, which helps resist excessive heat buildup in the fuse itself. This helps reduce the need for frequent fuse replacements, as the fuse will be able to more cleverly handle the same amount of current for a longer time period. In addition, the fuse is capable of sensing short circuit events, allowing it to automatically disconnect the circuit in such cases.The RLDP800UFF Resettable Fuse is designed for use in a wide range of voltage levels, from 14 volts to 800 volts. It is also capable of withstanding up to 5,000 amperes of continuous current and 20,000 amperes of repetitive peak current. The fuse can be mounted on a vertical, horizontal or inclined surface, making it suitable for use in different types of equipment, from appliances to automobiles.When the current overload ends, the RLDP800UFF fuse will automatically reset and allow the current to flow again like normal. This allows for quicker and more efficient circuit protection without having to replace the entire fuse element each time.Overall, PTC Resettable Fuses, such as the RLDP800UFF, are an incredibly useful circuit protection device, providing multiple advantages. They can handle a wide variety of voltage levels and withstanding vast amounts of amperage. At the same time, they are able to protect the circuit without having to be replaced, and automatically cut off power when an overload is detected. All these features make the RLDP800UFF PTC Resettable Fuse a great option for any application requiring reliable, effective and long-lasting protective elements.
