1210L175WR

PTC (Positive Temperature Coefficient) Resettable Fuses, such as the 1210L175WR, are thermal devices used to protect electrical and electronic systems from short-circuit and over-current scenarios and are being used more and more in consumer goods, appliances, batteries, motor protection, remote monitoring systems, unmanned systems, and other similar areas.Essentially, these types of fuses consist of a composite material, a polymeric material such as Polyvinyl chloride (PVC) mixed with an electrically active substance and a conductor, usually copper. The combination of these materials produces the PTC effect, which is a self-resettable feature, that when in an over-current situation the polymer increases its temperature and then enters its high resistance safe state, interrupting the current. No manual resetting is required, as once the short-circuit/over-current condition disappears, the temperature of the PTC cools and returns to its normal operating state. The 1210L175WR is a PTC Resettable Fuse that best operates at 175V / 175A, for up to 5s with a hold current of 115A and a hold time of 1 hour. It is about 12x10mm in size, has a typical time-to-trip of 300ms, and is classified as a 1A, 125V PTC, with a continuous current rating (IHold) of 175A. Its features include a surface mounted design, low power, high accuracy, and fast response time.These fuses are suitable for use in applications where a single PTC resettable fuse is used to protect against electrical shock or over-current conditions. This type of fuse is widely used in consumer products, home appliances, medical equipment, multimedia, and many other fields. It is also used in systems where the current requirement changes frequently, such as computers, audio systems, and power supplies. They are also suitable for use in motor protection, uninterruptible power supplies (UPS’s), portable communication systems, power supplies and power converters, controllers and circuit breakers. Furthermore, they are useful in applications requiring a short circuit protection time of up to 5s, providing fast interruption of the current. In the event of over-current, the PTC resettable fuse will deactivate, interrupting the circuit and preventing further damage to the components. It then will reset itself to its normal operating state once the cause of the over-current is eliminated. This provides extra security and protection from further potential damage. The 1210L175WR features an enhanced surface mounted design, allowing it to be easily implemented into a system with limited space. It also offers a low power and high accuracy, making it ideal for a range of applications. Furthermore, it has a fast response time, ensuring that in the event of any disturbances, the current is quickly interrupted. To conclude, the 1210L175WR PTC Resettable Fuse is a thermal device used to protect electrical and electronic systems from short-circuit and over-current conditions. With its enhanced surface mounted design, low power, high accuracy and fast response time, the fuse is suitable for use in consumer products, home appliances, medical equipment, multimedia and many other fields.
