PTC resettable fuses are a type of electrical fuse and overcurrent protection device that operates differently than traditional blade-style fuses. They are available in a variety of voltage and amperage ratings, and are typically used in consumer, automotive, and industrial applications.TRF250-180 is a Polymer Positive Temperature Coefficient (PPTC) resettable fuse that has a voltage rating of 250V AC/DC and current rating of 180A. This product is designed for use in a variety of electrical applications where overcurrent protection is needed.The working principle of a PTC resettable fuse is to use a material that has a positive temperature coefficient. This allows the device to increase its resistance with an increase of temperature. The increased resistance causes an increase in Read More current, which in turn causes the PTC fuse to heat up until a desired trip point is reached. Once this point is reached, the PTC fuse will open the circuit and stop unwanted current from passing through.To reset the fuse, the user simply needs to wait for the device to cool off. Once the temperature of the fuse has dropped to a safe level, the user can press the reset button, which will close the fuse. This process can typically take anywhere from a few minutes to a few hours, depending on the size and type of PTC fuse used.The TRF250-180 PTC resettable fuse can be used in a variety of applications, from industrial machinery to consumer electronics. This product is most commonly found in appliances such as refrigerators, dishwashers, and air conditioners. The PTC fuse can also be used in automotive applications, such as automotive batteries and circuit protection.The TRF250-180 PTC resettable fuse is designed to provide reliable overcurrent protection while still offering flexibility and convenience. It is simple to install, and can be reset quickly and easily when necessary. Additionally, the TRF250-180 PTC resettable fuse has a long life span and is designed to withstand high temperatures and humidity, making it a reliable and effective option for a variety of applications.
