7022.0420

Fuses are safety devices located in electrical circuits to protect against overloads. The 7022.0420 fuses are especially designed for motor applications, featuring a very high rated current, excellent thermal and electrical performance. It is part of a family of specially designed fuses, featuring a wide range of safety solutions for motor applications.

The 7022.0420 fuses have a rated voltage of 250 VAC and a rated current of 400 A. The wide range of current ratings enables them to be used in a variety of applications, including domestic appliances, small motors, lighting, and office equipment, among others. They have excellent overload protection performance and provide short circuit protection when needed. The 7022.0420 fuses are UL approved and are RoHS compliant.

A 7022.0420 fuse features two main parts: an aluminum core and a cylindrical metal enclosure. The aluminum core conducts the current between the terminals of the fuse. It is connected to the terminals with a crimp connection. The metal enclosure is designed to be durable and provides corrosion protection for the aluminum core. The enclosure also provides insulation, preventing current from leaking through the metal.

In operation, the 7022.0420 fuse works by using its aluminum core to restrict the current flowing through the circuit. When the current passes through the fuse, the aluminum core generates heat due to the resistance. If the current exceeds the rated current of the fuse, the heat generated is sufficient to melt the aluminum core and open the fuse, thereby breaking the circuit and protecting the circuit from damage due to overload.

In addition to providing overload protection, the 7022.0420 fuses are also self-resetting, meaning that once the overload current has been stopped, the fuse is automatically re-energized and the circuit is restarted. This makes the 7022.0420 fuse an excellent solution for applications where frequent overloading may occur. The low voltage drop of the 7022.0420 fuse also helps to reduce energy consumption in these applications.

The 7022.0420 fuses provide a reliable, compact, and cost-effective solution for motor applications and other electrical installations. They are designed to be easy to install and maintain, making them suitable for a wide range of applications. Their excellent safety performance and self-resetting capability make them an ideal choice for motor applications.
