Fuses

A fuse is an electrical safety device used to protect an electrical circuit from damage by excessive current, usually resulting from an overload or short circuit. The 0034.6981 is an example of a fuse; it is a U-Type, 250 Volt, and 2A ceramic fuse used for motor control and motor protection in various applications.

0034.6981 Application Field and Working Principle

Application Field

The 0034.6981 fuse is used mainly for motor control and motor protection applications, such as motor, ACDC, converter, and compressor applications. It is also suitable for use in battery or power supply circuits, and is used to protect electrical circuits from overloads and short circuits.

Working Principle

The working principle of a 0034.6981 fuse is that it is designed to vaporize when an excessive current passes through it. When the current reaches a predetermined value, the heat generated causes the fuse to vaporize, thus interrupting the current flow and preventing damage to the circuit.

The 0034.6981 fuse consists of a U-Type ceramic body with a silver-plated element running through its center. A metal strip is located above the element, which acts as an internal switch. When the current passing through the element reaches a predetermined value, the element will heat up and expand, thus triggering the metal strip switch and causing the current flow to be interrupted.

The 0034.6981 fuse is a cost-effective solution for circuit protection. Its design is such that it will only vaporize when an excessive current passes through it, and not when the current is lower than the predetermined value. This ensures that the circuit protection is reliable and effective.
