30R185UU

PTC Resettable Fuses are a specialized type of polymer-based overcurrent protection devices that contain a bi- Metallic strip that melts when an overcurrent situation occurs and then after a timeout, they reset and work again. 30R185UU is one such type of Resettable Fuses that are widely used for over current protection.

Application Field:

30R185UU PTC Resettable Fuses are mainly used in the appliance, electronic and automotive markets. They are also widely used in cell phones, batteries, computers, cordless power tools, laptops, LCD TVs, air conditioning, lighting, Electric vehicles and many other applications. Furthermore, they can be used as protection devices for any application with a maximum continuous current rating of 18.5A.

Working Principle:

The working principle of 30R185UU PTC Resettable Fuses lies in its two different states, namely an active state and an inactive state. During the active state, these resettable fuses act like a switch to allow the current to flow if it is below the maximum current rating (18.5A). However, when the current reaches and exceeds the maximum current rating, the bi-metallic strip absorbs the excessive heat and melts, thereby opening the circuit and creating an inactive state. After a certain period of time (usually between 10 to 30 seconds), the bi-metallic strip cools down and resumes its original shape, reconnects the circuit and the PTC Resettable Fuse is ready to work again.

Benefits:

30R185UU PTC Resettable Fuses offer a number of benefits as compared to other types of fuses and circuit breakers. Firstly, they are much more reliable and efficient since they take into account a wide range of overcurrent situations. Secondly, the resetting action is very quick and efficient, which means there is very minimal downtime for any product incorporating the PTC Resettable Fuse. Additionally, 30R185UU PTC Resettable Fuses can be used in parallel with other types of fuses, providing more options for manufacturers.

Conclusion:

30R185UU PTC Resettable Fuses are an efficient and reliable form of overcurrent protection for a variety of different industries. They provide quick and easy resetting action, which greatly improves the reliability and efficiency of the products they protect. Furthermore, 30R185UU PTC Resettable Fuses can also be used in parallel with different types of fuses, providing more options for manufacturers.
