Fuses
Fuses are electrical safety devices that protect electrical circuits and equipment from overload and short circuits. 0674007.DRT4 is a type of fuse specially designed to serve as over-current protection for communications, sound, and instrumentation circuits in control panels and junction boxes.
Application Field
0674007.DRT4 fuses are used in control panel, distribution board, and junction boxes to protect electrical equipment from overloads and short-circuit current. These fuses are ideal for low current, low voltage applications, and are suitable for use in 4 to 35 Volt DC circuits, or AC circuits up to 600 V. The Designed Rejection Toe portion serves the added benefit of interrupting current when the voltage potential between two points of the circuit become significantly different.
Working Principle
0674007.DRT4 fuses are comprised of a tubular element made of an alloy of silver, copper and lead encased in a glass or ceramic envelope. An integrated metal cap encompasses the metal element of the fuse, forming a seal to maintain an air-tight environment. This metal element is the conduction path that current flows through. When an abnormal amount of current flows through the element, it heats up and causes a rapid increase in the internal pressure of the element, breaking the seal and thus interrupting the flow of current.
In addition to the tubular element, 0674007.DRT4 incorporates a concept called Designed Rejection Toe (DRT). DRT gives the fuse an additional capability known as application rejection. Application rejection is when the fuse will not allow its insertion into a misaligned socket. As an example, the wrong fuse cannot be inserted into the incorrect voltage (i.e. A 32 Volt fuse in a 12 Volt socket). The DRT serves as an additional layer of protection to the circuit.
