Introduction to 5TT 1

5TT 1 is a form of protection in power distribution networks. It provides short circuit protection for the purpose of safeguarding the integrity of the electrical system and preventing possible physical damage due to oversized current.

Application Field

5TT 1 is mainly used in some large-scale projects including power generating plants, electric utilities, industrial manufacturing plants, and electric distribution systems. It is mainly used to provide line protection in electrical networks to prevent the line from being damaged due to short circuit and overcurrent. As a precautionary measure, the 5TT 1 should be located at the entrance of each circuit, such as the bus, outgoing line, and main incoming line.

Working Principle

The 5TT 1 works by over-voltage protection and under-current protection. When an overload current occurs, the fuse will blow, interrupting the circuit and preventing damage from occurring. The 5TT 1 also has over voltage protection, which means when the voltage exceeds its rating the fuse will blow, again preventing damage or disconnecting the circuit.The 5TT 1 fuses are constructed with a metal element that is prone to melting at a certain temperature depending on the current. When the current exceeds a pre-set level for example, the heat generated by the current causes the metal element to melt, thus interrupting the circuit flow. The current is then disrupted and the circuit is protected from damage.

Conclusion

5TT 1 provides effective protection for electric lines and components in high-power applications and is designed to limit current and prevent damage due to system overloads. The working principle of this type of fuse is the heat generated by an overload current causes the metal element to melt, interrupting the circuit and protecting it from further damage. Overall, it is an essential part of power distribution systems for both safety and security.
