Fuses

Fuses are common electrical components found in virtually all applications of electrical engineering. They are designed to protect electrical circuits by preventing damage from shorts or surges. This article will discuss the application and working principle of the 0662002.ZRLL fuse.

Application Field

The 0662002.ZRLL fuse is a current-sensitive device that is used to protect equipment from short circuits, overcurrents, and dynamic or static current overloading. It is commonly used in electrical power distribution systems, industrial control circuits, and military systems. It is rated for 125 A continuous current and 250 A intermittent current. It is also UL approved, UL 94V-0 rated, and CSA approved.

The 0662002.ZRLL fuse is capable of withstanding a wide range of temperature extremes. It has a temperature range of -55°C to 135°C, which makes it suitable for temperature-sensitive applications. It is also capable of containing electromagnetic interference, which makes it a suitable choice for applications where EMI is a concern. With its low-power, miniature size, and a wide range of options, the 0662002.ZRLL fuse is a very desirable choice for a variety of applications.

Working Principle

The 0662002.ZRLL fuse is a current-sensing device. It works by measuring the amount of current flowing through the fuse and triggering the opening of the fuse when the current exceeds the rated current. This is done by measuring the voltage drop across the fuse, and when the voltage surpasses a predetermined threshold, the contacts of the fuse open and the current is interrupted.

When the current decreases below the rated current, the fuse will reset itself and close the contacts. This process will continue until the source of the overcurrent is addressed. The 0662002.ZRLL fuse is also able to detect regenerative and dynamic current surges, and will open the contacts to protect the system from damage.

The 0662002.ZRLL fuse also has intrinsic protection against arc shorting. When the arc current is detected, the fuse will open the contacts and prevent the arcing from continuing.

Conclusion

The 0662002.ZRLL fuse is a widely used electrical component with a variety of applications. It is a current-sensing device that protects systems from short circuits, overcurrents, and dynamic current surges. It is capable of withstanding extreme temperatures, contains EMI, and has intrinsic arc protection. It is UL-approved and CSA-rated, and is ideally suited for industrial control circuits, power distribution systems, and military systems.
