PTC Resettable Fuses 0ZSA0120FF1E is a kind of polymer PTC fuse, which is widely used for the overcurrent protection of industrial power systems, solar, UPS, LED lighting, computers, communications, ovens, home appliances, and other products, as well as accompanying circuit boards and distributed power supply devices. Application-specific features including adequate short-circuit holding current, low power dissipation and fast response time allow for current limiting protection against short circuits.

In contrast with traditional fuses, PTC resettable fuses don\'t need to be replaced after tripping and allow for multiple tripping cycles. That said, once the current overloading situation is eliminated, the device automatically returns to its operational state by heating up and resetting. The process is instantaneous, meaning just a fraction of a second.

The 0ZSA0120FF1E comes with a rated current, reset current, maximum voltage and many other parameters. The rated current and reset current are two critical parameters as they indicate the device\'s protection level during overcurrent events. Therefore, it is essential to have full knowledge of the applicable system. It is also crucial to choose the appropriate fuse for the application; otherwise it can cause considerable damage to the equipment.

When the current flowing through the PTC Resettable Fuses 0ZSA0120FF1E exceeds the specified Maximum Operating Current (MOC), the internal resistance increases abruptly due to the combined effect of the resistance and the increasing temperature. This causes the current to be limited until it decreases to the level of the specified Reset Operating Current (ROC). As the device is temperature dependent, a certain number of seconds is required to reset it, providing time for the protect system to take appropriate action.

In summary, PTC Resettable Fuses 0ZSA0120FF1E are efficient and reliable devices designed for overcurrent protection. They offer fast response, low power dissipation, multiple tripping cycles and easy resetting, making them a great choice for a wide range of applications.
