What is 5591-01 Fuseholders?

5591-01 fuseholders are device designed to hold and electrically connect fuses for protection of electrical circuits. This type of fuseholder replaces the traditional screw-in fuse holders, making them easier to install, maintain, and replace. The fuseholders mount directly onto a power panel, terminal box, or an electrical junction box. They are constructed with an all-metal housing to fit securely into the designated power panel or terminal box. The contacts of 5591-01 fuseholders are made of silver (Ag) so that they remain intact even after thousands of electrical connection cycles.

What are the application fields of the 5591-01 Fuseholders?

The 5591-01 fuseholders are commonly used in industrial process control applications to protect against overloads in electrical circuits. They can also be used in motor control systems, control panels, motorized equipment, electro-mechanical systems, high current relays, and AC/DC power supplies. They are ideal for applications where a solid connection is required to provide a reliable source of current. These fuseholders are often utilized in automotive and industrial environments where high current levels are necessary. In certain applications, the 5591-01 fuseholders are used in conjunction with fuses to provide an additional level of circuit protection.

What is the working principle of the 5591-01 Fuseholders?

The working principle of 5591-01 fuseholders is similar to the traditional screw-in type fuse holders. When a fuse is inserted into the holder, the contact points are pressed together with a spring-loaded mechanism. This creates a secure electrical connection between the fuse and the holder, allowing current to pass through the device. In the event of an overload, the fuse will blow, cutting off the electrical connection and protecting the circuit. The fuseholder itself is designed to withstand the high current levels generated by the overloads.

The 5591-01 fuseholders are also equipped with an open fusible link in the event of an open circuit. This links prevents contact between the fuse and the holder when the circuit is open, thus isolating the fuseholder from the circuit. This additional feature provides a double layer of protection for the circuit, ensuring that it is never exposed to dangerous currents.

Conclusion

The 5591-01 fuseholders are designed to ensure a secure connection between electrical devices and fuses for current protection. The all-metal housing and Ag contacts make them especially suitable for harsh electrical environments. They are ideal for applications where high current levels are needed, including industrial process control, motor control systems, control panels, electro-mechanical systems, high current relays, and AC/DC power supplies. The fuseholders are also equipped with an open fusible link that prevents contact between the fuse and the holder when the circuit is open. This provides an additional layer of protection for the circuit, ensuring that it is never exposed to dangerous currents.
