Introduction

120AFEE is a type of electrical specialty fuse used for short-circuit protection. This fuse is designed to be used in a wide variety of applications such as lighting, automotive, industrial, instrumentation, and commercial. This fuse has become the preferred choice for many in the construction and electrical trades for its reliable protection against electrical hazards. In this article, we will discuss the application field and working principle of the 120AFEE fuse.

Application Field of 120AFEE Fuse

The 120AFEE fuse is used for short-circuit protection in a range of applications. Its applications include lighting, automotive, industrial, instrumentation, and commercial. In lighting, this fuse is used to provide short-circuit protection in LED light fixtures and fluorescent ballast. In automotive, it is used to protect starter motors, alternators, and battery charging systems. In industrial applications, the 120AFEE fuse is used to protect motor circuits, pump systems, and HVAC systems. In instrumentation, it is used to protect various types of circuit boards and DC power supplies. In the commercial sector, this fuse is used to protect fire alarm and security systems, as well as telecommunications equipment.

Working Principle of 120AFEE Fuse

The working principle of this type of fuse is based on the fact that it can withstand short-circuit current. When the current flowing through the fuse exceeds its rated amperage, it will melt open, thus breaking the circuit and preventing further current from flowing. In most cases, the fuse will not be able to fully recover after a short-circuit current has been applied, and will need to be replaced. This is why it is important to always use the fuse with the proper amp rating for the application it is being used for.

The fuse is made up of a metal strip that is crimped onto a pair of terminals and insulated from the fuse body. Inside the fuse, there is a metal wire or ribbon between the terminals. This wire will heat up when the current exceeds the rated amperage. This heat melts the wire, thus interrupting the current and preventing further damage. The fuse is designed to open within a few milliseconds of exceeding its amp rating, so that it can protect against possible electrical hazards.

Conclusion

The 120AFEE fuse is a type of electrical specialty fuse used for short-circuit protection. This fuse is used in a variety of applications, including lighting, automotive, industrial, instrumentation, and commercial. The working principle the fuse is based on the fact it can withstand short-circuit current. When the current exceeds the rated amperage, the metal wire or ribbon inside the fuse will heat up and melt, thus interrupting the current and preventing further damage from occurring. The 120AFEE fuse is a reliable and cost-effective way to protect against short-circuit related electrical hazards.
