Fuseholders

The 04820001ZXB is a fuseholder, designed for applications where high reliability, short circuit current rating and maximum usage flexibility are essential. It is rated to safely contain and break blown fuses by offering the highest allowable short circuit current rating without the need for any additional parts. This feature allows the ANSI 4840 fuseholder to be used for applications with the highest short circuit ratings.

Application Field

The 04820001ZXB fuseholder is most commonly used in industrial applications such as fuse protection of critical electrical networks to prevent damage or malfunction from sudden power surges and overcurrents. It is also ideal for applications such as AC motors and electronic power controllers. For these applications, the fuseholder must have an ample margin of protection and the capability of breaking the fuses with minimum arcing, so that the safety of the equipment as well as people in the vicinity is not compromised.

Working Principle

The working principle of the 04820001ZXB fuseholder is simple yet effective. The fuseholder is constructed with a set of two spring-loaded contacts and a pin insert. When a fuse is installed, the contacts clamp onto the fuse’s terminal ends, thereby establishing an electrical connection with the insertion pin. When an overcurrent occurs, the interior elements fuse together, thus breaking the connection between the contacts and the pin, and also triggering the fuse to blow.

The 04820001ZXB fuseholder is designed with high-reliability features such as an offset contact design to reduce the stress on the fuse terminals and stainless steel contacts for superior contact mating and corrosion resistance. The offset design also reduces noise and contact bounce, while the stainless steel contacts ensure reliable contact connections. The design also prevents arcing, ensuring safe operation even under high-short circuit currents.

In addition, the 04820001ZXB fuse holder’s modular design allows it to be used for both standard and custom high-reliability applications. The fuseholder also features integral lightening protection, fire-resistant insulation and low-voltage air disconnect. It also offers a wide range of mounting options, such as pre-wired onto a circuit board or countersink screws for surface mounting.

Conclusion

The 04820001ZXB fuse holder is a reliable and safe fuseholder designed specifically for applications requiring high reliability, short circuit current rating, and maximum usage flexibility. Its offset contact design reduces stress and noise, while its stainless steel contacts ensure reliable contact connections. Its modular design allows it to be used for both standard and custom purposes, and its wide range of mounting options makes installation easy. With the 04820001ZXB fuseholder, you can be sure your critical electrical networks are protected.
