FCD121315TP is a one-time ceramic fuse provided by TOYO. It has a wide application field and can significantly improve the safety of power systems. In this article, we will talk about the application field and work principle of FCD121315TP.

Application Field

The FCD121315TP has a high current capability and can handle a maximum current up to 250A. It is especially suitable for low voltage circuit in industrial area such as capacitor charge, electric welding, household appliances, light decoration, monitoring system and security system. In addition, the FCD121315TP also has excellent capabilities to handle the surge current, high surge capability and lightning protection. It is most commonly used in circuit protection and lightning protection.

Working Principle

The FCD121315TP is a one-time ceramic fuse, which means it can only be used once, and after a single fault trip, it has to be replaced by another fuse. When power overloading happens, the FCD121315TP will heat up to a certain temperature and release the melted fuse element to separate the circuit and protect the system from damage. When the current is returned to its normal level, the FCD121315TP can not restore the circuit automatically, and a new fuse element needs to be replaced before the system can be used normally again.

In addition to having current and surge protection capabilities, the FCD121315TP also has high dielectric strength and is very safe in high temperature environment. The operating temperature range of the FCD121315TP is -55℃ to +130℃. It is also highly reliable and has a long service life, the lifetime of the FCD121315TP is usually up to 10,000 hours or more.

Conclusion

The FCD121315TP is a one-time ceramic fuse designed and produced by TOYO. It provides excellent protection for low voltage circuit such as capacitor charge, electric welding, household appliances, light decoration, monitoring system and security system. It has high current capability, excellent surge capability, lightning protection, high dielectric strength and long service life. It is an indispensable element in the power system, which ensures the safety of the entire system.
