PTC Resettable Fuses are an important component in the safeguarding of electrical circuits and systems. The 72R160XMR application field and working principle of these fuses has been developed over the last few decades to provide maximum efficiency and safety in circuits and systems subject to intense electrical loads. PTC Resettable Fuses are designed to isolate an electrical circuit in the event of an overload or short circuit. The use of this fuse type allows for the continued functioning of the circuit, without the need for resetting the fuse itself. This makes for a much more reliable and safe electrical system. A 72R160XMR PTC Resettable Fuse is made up of a Thermally Resettable Polymer-PTC fuse element, which has been designed to trip and reset at specific temperatures. It is composed of a polymer material which can generate a self-regulating current when subjected to an electrical current. This self-regulating current is then divided between two contacts, which trips the fuse and stops the flow of current. The Tripping Temperature of the PTC Resettble Fuse is determined by the intrinsic resistance of the material itself. The material behaves in such a way that when the operating current is below a preset level, the current is conserved with minimal resistance, however when the current exceeds the preset threshold, the material releases a preset amount of energy. This energy is then dissipated as heat, causing the PTC Resettable Fuse to trip. Once the fuse is tripped, the self-regulating current ceases, and the fuses will automatically reset once the heat dissipates and the current drops below the preset threshold. This allows the fuse to be used in multiple applications, providing a reliable and efficient safety mechanism for electrical systems. The 72R160XMR PTC Resettable Fuse has an inherent current ranging from 0.72A to 16A and an operating temperature range of -40 to 80°C, allowing it to be used in a variety of different applications, including telecommunications, automotive and consumer electronics. It serves as an efficient way to isolate electrical circuits, protect circuits from damage, and prevent fires from caused by uncontrolled electrical currents.PTC Resettable Fuses are suitable for a variety of applications where space is at a premium, as they are much smaller than conventional fuse types. Additionally, due to the self-regulating nature of the fuse design, the life expectancy is much longer, requiring less servicing and maintenance than conventional fuse types.Overall, the 72R160XMR PTC Resettable Fuse is a highly effective and reliable electrical safety component which can provide maximum protection for electrical circuits and systems. The inherent high temperature rating of the fuse makes it suitable for use in a range of different environments, providing maximum protection for electrical circuits in the event of an overload or short circuit.
