0665001.ZRLL Application Field and Working Principle

The 0665001.ZRLL is a type of fuse from the 066 Series manufactured by Littelfuse. It is a low voltage-drop fuse suitable for protecting electronic circuits from excessive currents, thus reduces the risk of damage or destruction. The fuse provides overload protection and short-circuit protection in a DC power circuits, enabling it to be used in automotive, marine, backup power systems and many other applications. 

Application Field and Design

The 0665001.ZRLL is designed to be used in DC power circuits, and its small size and higher interrupting ratings makes it particularly suitable for protecting low-voltage circuits. Its low-voltage drop characteristics and high current-carrying capacity are especially valued in vehicle applications, such as in automotive and marine systems. In addition, the small size of the fuse, with an overall length of 11.2 mm and a diameter of 6.6 mm, enables it to be incorporated into space-restricted applications. The fuse is designed with a single-piece construction and has a lightweight brass body and a low-resistance nickel-plated metal element, which make electrical contact with the body when the current exceeds the rated value.

Working Principle and Features

The 0665001.ZRLL operates by the melting of the fuse element which occurs when the current exceeds the rated value and causes the continuity of the circuit to be interrupted. This ensures the protection of the circuit from overload and short-circuit conditions. The fuse has an operating temperature range of -30 to 85 degrees Celsius and is designed to be used in circuits with voltages up to 32V, and currents up to 1350 A. The fuse can be mounted on a panel or printed circuit board, and includes a threaded barrel for reliable mounting. The fuse also has an IP67 ingress protection rating, making it resistant to dust and water.

Conclusion

The 0665001.ZRLL is a fast-acting fuse designed for DC power circuits, providing effective protection from overload and short-circuit. Its high current-carrying capacity, small size and low-voltage drop characteristics make it ideal for automotive and marine applications, as well as other space-restricted applications. In addition, the fuse has an IP67 rating and can be mounted on panels or printed circuit boards, making it reliable and easy to use.
