3414.0112.22.M Application Field and Working Principle

The 3414.0112.22.M is a type of fuse used widely in a variety of applications. It is a current interrupting device designed to provide a safe disconnect of an electrical circuit when an electrical overload, short circuit, or other dangerous conditions occur in the network.

Application Field

The 3414.0112.22.M fuse is suitable for the medium and small power distribution network up to 1000 volts AC, or 1250 volts DC. It is used mainly in the low voltage distribution networks, such as 10kV/12kV, for overcurrent and short-circuit protection of power lines, power transformers, generators, motors, distribution wiring, and other power sources. It can also be used in lighting systems, air conditioners, solar energy systems, and so on.

Working Principle

The core of the 3414.0112.22.M fuse is to absorb the overcurrent that occurs during an overcurrent or short-circuit event. The fuse is composed of a copper tube surrounded by a thin wall of glass or ceramic, functioning as a current-carrying conductor. When there is an overcurrent or short-circuit event, the current will travel through the copper tube, which will generate heat quickly and melt the surrounding glass or ceramic wall. This will rupture the wall, interrupting the current and providing a safe disconnect of the system.

In addition, the 3414.0112.22.M fuse also offers overload protection, in which a slightly higher than normal current will cause the fuse to "trip" and shut down the system, protecting it from permanent damage.

Conclusion

The 3414.0112.22.M fuse is a reliable and cost-effective way to protect electrical systems from transient overcurrents, short circuits, and overloads. Its application field is various, and its working principle is easy to understand.
