PTC Resettable Fuses are an effective safeguarding option for preventing damages due to overcurrents in electronic devices. They provide both overcurrent protection and resetting capability, making them an ideal solution for many applications. One of the most popular types of resettable fuses is the 600R160-RAF, which is widely used in a variety of industries due to its excellent performance and reliability. This article explores the application fields and working principle of the 600R160-RAF PTC Resettable Fuses.

The 600R160-RAF is particularly suitable for applications where a low hold current and a high breaking capacity are required. This type of fuse is most commonly used in telecommunications devices, medical equipment, audio/video equipment, home appliances, and automotive vehicles. It is also highly suitable for battery charging protection and protection against overload conditions in a variety of electronic and electrical products.

The 600R160-RAF offers a maximum interrupting rating of 160A and is rated for up to 6,000V surge testing for capacitive loads and 4,000V surge testing for resistive loads. It can operate effectively under extreme temperatures of -55°C to 125°C and offers a hold current of 6A. This fuse also provides high surge absorption and short circuit protection, making it a reliable choice for long-term use.

The 600R160-RAF PTC Resettable Fuses are based on the principle of polymeric positive temperature coefficient (PPTC). This type of fuse is composed of a piece of conductive material, such as polyacetylene or polyurethane, with a metal electrode on either side. When a current is applied to the PPTC material, the material will heat up and expand due to its high resistance properties. This will cause the electrode on both sides to come into contact, effectively interrupting the current and cutting off electricity.

When the current is removed, the PPTC material will slowly cool down and contract, allowing the electrodes on either side to separate. This will reboot the fuse and allow for a normal current flow. This process, known as “thermal resetting”, makes the 600R160-RAF a safe and effective solution for protection against short circuits and overloads.

The 600R160-RAF PTC Resettable Fuses offer superior performance and reliability in a small, lightweight package. They are easy to install and require no maintenance, making them an ideal choice for many applications. These fuses provide effective protection and resetting capability, making them an indispensable component in many electronic devices.
