5TTP 400

5TTP 400 Application Field and Working Principle

The 5TTP 400 is a type of fuse that is designed for applications in the field of industrial electric power systems. It is used to protect against overcurrent and short-circuit conditions for equipment and cables.

The 5TTP 400 fuse is rated for AC or DC applications up to 400 Amperes. It is constructed of a rigid, impact-resistant thermoplastic shell and fitted with a high-temperature, silver alloy element. The element is assembled into a grooved disc or bar located in the middle of the cartridge.

The 5TTP 400 fuse operates on the basic principle of current interruption. As the current through the fuse element passes the designed interrupting rating, the element melts and interrupts the circuit. This action occurs within milliseconds, providing overcurrent protection for the applications.

The 5TTP 400 fuse is designed to provide protection against both overloads and short circuits, and has a wide variety of applications in industrial electric power systems. It is designed for use in lighting and thermal circuits, machine drives, transformers and other equipment. It can also be used as a service-entrance fuse for residential and commercial buildings.

The 5TTP 400 fuse is a highly efficient protective device for use in industrial power systems. It is easy to install and provide reliable, consistent protection against various types of overcurrent and short-circuit conditions.
