PTC Resettable Fuses have been an integral part of circuit protection technology for many years. PTC resettable fuses are widely used in all kinds of products, including portable electronic devices, DC power lines, automotive systems, telecommunications systems, and consumer appliances.The PTGL4SAS220K4N51B0 is a PTC Resettable Fuse that is rated up to 220A (AC/DC). It offers a wide range of applications, including over-current and over-temperature protection in general-purpose electronics and peripherals, LED lighting, motor protection, power supplies, and automotive applications.The PTGL4SAS220K4N51B0 PTC Resettable Fuse is designed to help protect against over-current and over-temperature events, and is also suitable as a form of fuse protection in automotive systems. It can be used in applications ranging from 60 VDC to 400 VAC (max. 500 V impulse). It offers a fast response time of 1 ms (max.) and a low resistance of 6mΩ (typ.).

The fundamental working principle of a PTC Resettable Fuse is that it contains a Positive Temperature Coefficient (PTC) material, which is a material that has a temperature-dependent resistance. The PTC material is in contact with two electrical terminals, and the resistance increases as the temperature rises. When an over-current or over-temperature event occurs, the PTC material will heat up and its resistance will increase. This raises the temperature even further, acting as a self-sustaining process and causing the PTC Resettable Fuse to trip. Once the fault condition has been removed, the PTC material will cool down and the device will reset itself.

The PTGL4SAS220K4N51B0 PTC Resettable Fuse is classified as an IEC 127-2 type K fuse. This means that the fuse is suitable for applications where the protective device is required to interrupt the current without requiring a human operator. The fuse is available in a wide variety of sizes and ratings, making it suitable for a variety of applications.

The PTGL4SAS220K4N51B0 PTC Resettable Fuse is designed for use in a wide variety of applications, including consumer appliances, automotive systems, electronic control systems, and power supplies. The device offers reliable protection against over-current and over-temperature events, and due to its fast response time and low resistance, it is an ideal choice for a variety of applications. Finally, the device meets all of the necessary safety standards for use in a broad range of applications.
