PTC Resettable Fuses are commonly used in a variety of applications including consumer electronics, medical devices, industrial and automotive. The PTC (positive temperature coefficient) resettable fuse is a one time operation bridge that will open up when an over-current occurs, cutting off the power supply. The device is designed to reseal itself after the current pulls below the pre-determined level. Unlike traditional fuses that have to be replaced after they have been ‘blown’, PTC resettable fuses can be reset to its factory default settings and continue operation.

PFRY.160 Application Field and Working Principle

The PFRY.160 is a type of PTC Resettable Fuse that is specifically designed for industrial and automotive applications. This fuse has a higher current handling capacity and is ideal for applications with high starting current such as automotive, traction motors, and wind turbines. The PFRY.160 is rated from 10A to 160A and offers a wide range of temperature ratings -40°C to +85°C.

The basic principles of PTC resettable fuses are simple. The device works by sensing an over current condition and opening the bridge to stop the current from flowing. During normal expected voltage variations the fuse will not open, but when there is a large over current or short circuit situation the fuse opens up. There is an temperature coefficient which determines when the fuse will open and how quickly it will open, this ensures that it can perform in a wide range of temperature environments.

The PFRY.160 is typically placed in series within the power line and can be used in applications such as motors, control relays and other electronic components. It\'s robust design and wide temperature range makes it ideal for harsh operating conditions. The normal insertion loss of the fuse is 0.045mΩ, it offers very low leakage current allowing it to be used in high power applications.

When combined with proper over current protection, the PFRY.160 can be used as a primary over current protection device. It is a preferred choice for automotive, medical, and other industrial applications because it is rugged, easy to install, and capable of resetting itself after a fault is cleared. After the fuse opens up, it will reset to its initial settings after a cooling off period and will be ready for use again. This helps avoid the need to replace the fuse.

The PFRY.160 is a cost effective and reliable over current protection solution that is ideal for a variety of applications where a robust fuse with high temperature resistance is needed. The robust design makes it a reliable choice in harsh environments while the ability to reset itself ensures minimal downtime. As long as proper installation practices and working technique is used, the PFRY.160 PTC resettable fuse can provide efficient over current protection for years.
