PTC Resettable Fuses can provide over current protection, and their simple resetting makes them extremely cost effective. The MF-RX185/72-0-14 is one such fuse, and is widely used in various applications. This article outlines the various application fields of this PTC resettable fuse, as well as its working principle.The MF-RX185/72-0-14 PTC resettable fuse is mainly used for various electronic products, such as consumer products, etc. It is a perfect choice for protecting against overcurrent and short circuit conditions. It automatically resets itself after it has tripped, saving the user time and money. It is also widely used within power sockets, power strips, adapters, electrical appliances, industrial and commercial products, various usb charging, and data line protection.The MF-RX185/72-0-14 has a current rating of 72A and a voltage rating of 85VAC. When the current exceeds the rated value, its over-current protection element will open and cut off power supply. After the current is reduced to a certain level, it will automatically reset itself. It\'s features include robust construction, low power consumption, and improved safety. In addition, this PTC resettable fuse also offers advantages like being designed for high insertion force with long contact life, compact size, and a variety of mounting styles. The working principle of the MF-RX185/72-0-14 is quite simple. It functions as a switch, connecting or disconnecting the current path. Its active element has a heat-sensitive element, which is usually a ceramic disk. This element is placed in the circuit and when it is subjected to a current higher than the rated value, it will expand the contact gap and thus disconnect the current path. When the current returns to normal, the contact gap will return to its original state and the circuit will be re-connected. This is how the PTC resettable fuse works.In conclusion, the MF-RX185/72-0-14 PTC Resettable Fuse is an ideal choice for various applications. Its current rating of 72A and voltage rating of 85VAC makes it suitable for a variety of consumer, industrial, and commercial products and applications. Its simple resetting mechanism allows it to be used in cost-effective ways and offers users improved safety. Finally, its working principle is quite simple, making it a reliable and easy to use fuse.
