PTC Resettable Fuses

PTC Resettable Fuses, more commonly known as Polymeric Positive Temperature Coefficient Resettable Fuses (PPTCRs) are designed to ensure an utmost safety against over-current and short circuit conditions. The most common application of PTC Resettable Fuses lies in consumer electronics and industrial networks, like automotive, telecommunications, and consumer appliances, among others.This type of fuse comprises a polymeric material that is susceptible to changes in temperature. This polymeric material helps to create a low-resistance current path that increases current flow. As the current increases, so does the temperature, eventually reaching a critical resetting temperature. At this point,the fuse opens, and current flow is blocked.PTCCL11H701DTE is a unique type of PTC Resettable Fuse that is widely used in a range of industrial and automotive applications. The PTCCL11H701DTE fuse is suitable for use in protecting lines used for DC power, including home appliances, automotive, and industrial wiring needs. This fuse is typically used in the automotive industry to protect wiring against short circuits and overload conditions.In terms of performance, the PTCCL11H701DTE fuse offers an excellent thermal stability, features a fast response time and minimal contact resistance. It has a rated current of 70A and an operating temperature range of -55°C to 125°C.The working principle of a PTC Resettable Fuse involves a unique combination of material properties and construction. The preferential orientation of the molecule chain of the sensor element is balanced with a terminal portion connected in parallel to the element and connected by a membrane bridge to the heat sink. A voltage is applied to the sensor bridge through the heat sink and the terminal portion. When the current flows through the fuse, it produces heat which increases the temperature of the fuse. This increase in temperature causes the polymer to lose its polarization and to increase its internal resistance. This rise in internal resistance results in a current decrease of the fuse and eventually a cut off state. After the temperature decreases, the fuse is automatically reset and the current can flow again.The PTCCL11H701DTE PTC Resettable Fuse has proved to be a reliable and effective solution for protecting sensitive electrical components. Thanks to its fast response and excellent thermal stability, it is suitable for both commercial and industrial applications. It is small in size, energy efficient, environmentally friendly and very affordable, making it a cost-effective choice for a wide range of needs.
