0TOO.400Z

0TOO.400Z Application Field and Working Principle

The 0T00.400Z is a type of electrical specialty fuse, used to control and protect electrical devices. It is an axial lead device, protecting against overloaded or short-circuited circuits. This fuse is designed to melt rapidly on overload, thus isolating the circuit from any potential damage. It is mounted in position with a solder-seal connection or crimp seal.

Application Field

The 0T00.400Z is most often used in applications with low amperage, such as household circuits and automotive wiring, and in the manufacture of electrical components, such as light bulbs, motherboards, and resistors. It can also be used in industrial and commercial settings, for the protection of control circuits, motors, transformers, and relays. These fuses are designed to meet a variety of standards and specifications.

Working Principle

The 0T00.400Z specialty fuse utilizes a metal matrix to conduct electricity. This matrix is designed to quickly melt on overload, thus disconnecting the circuit. The fuse is designed to disconnect power faster than a switch, allowing the system to remain inoperative until the danger has passed. The matrix contains a mixture of metals that are chosen for their resistance to melting, including nickel, aluminum, and tin.

When the 0T00.400Z fuse is overloaded, heat is generated due to the resistance in the metal matrix. This heat is transferred to the fuse body, eventually causing the matrix to melt and separate. At the same time, the blowout element, which is made of brass, opens to relieve the pressure on the contacts. This prevents damage to the contacts and prevents a fire from starting.
