Fuses

Fuses are a form of overtemperature protection device designed to protect the electrical devices, circuits as well as other components when the current surpasses the safety limit. 0251.250PA T1L is an example of a fuse that belongs to this category of protective devices. This small size fuse has low breaking capacity, meaning that its low temperature withstands currents just sufficient to interrupt sensitive circuits.

Application Field of 0251.250PA T1L

0251.250PA T1L is ideal for protecting the circuits used in audio-visual apparatus and measuring instruments, especially in small sizes. It is suitable for AC 50 Hz to 60 Hz and rated to 250 Vac. It can also be utilized in mobile phone chargers, additional components in machinery, and other related applications. Thanks to its low breaking capacity, it is used in numerous circuits with a more sensitive nature, such as capacitors on mobile phone chargers.

Working Principle of 0251.250PA T1L

The working principle behind 0251.250PA T1L is relatively simple. When the current passes through the fuse, and it exceeds the set limit (which is specified by a label), the fuse will open the circuit. The fusing action is a result of the heat generated by the electric current. These heats are localized and result in the melting of the metal links that path the current.

As the elements inside the fuse heater up, they will expand and the fuse clip will open. The moment the fuse clip opens, the electric current will be disrupted, and the danger eliminated. The 0251.250PA T1L contains a single-element linked to the terminal, which will expand as it’s heated. This movement of the element will open the fuse link.

Conclusion

0251.250PA T1L is a type of fuse that can be used in diverse electronic applications with high current sensitivity such as audio-visual equipment, measuring instruments, and other mobile phone related applications. Its working principle basically involves the disruption of the electric current when the temperature crosses the threshold limit.
