Fuses

A fuse is a mechanical device used to protect electrical circuits from being overloaded. This protection is achieved by the fuse breaking an electrical circuit, at a predetermined current level. Fuses come in many forms; some have solid wire links, while others feature re-settable breakers, which are reset after each trip. Fuses are commonly made from PCBs, metal wires and other materials, depending on the application. 5TT 400-R fuses are an example of a common type of fuse, used in a variety of applications.

5TT 400-R Fuse Application Field

The 5TT 400-R fuse is a commonly used type of circuit protection device, suitable for use in applications topping 200 Amps. Its application field consists of power distribution systems, equipment and tools, vehicle wiring, and sometimes even electric propulsion motors. This type of fuse is commonly used in large distribution systems, due to its high current tolerance and ability to open circuits quickly. It is also used in many hoists, belt drives, control boards, and air conditioning systems.

5TT 400-R Working Principle

The 5TT 400-R is a three-phase, low-resistance fuse. In basic terms, it works by gradually increasing resistance as the current passes through the circuit. If the current exceeds the fuse\'s rating, its internal resistance becomes too high, causing the fuse to become thermally disrupted. The disruption can take the form of melting the fuse, breaking off the contacts or wires, or disrupting the circuit due to the excessive heat generated. When the circuit is disrupted, the power to the device is cut off, thus preventing any further damage.

Conclusion

The 5TT 400-R is a type of fuse commonly used in power distribution systems, vehicle wiring, and other high amperage applications. Thanks to its high current tolerance and quick circuit disruption, the 5TT 400-R is an ideal choice for protecting electrical circuits from overloads. When used properly, it can significantly reduce the risk of damage from shorts and surges. Hopefully, this article has given you a better understanding of the application field and working principle behind the 5TT 400-R fuse.
