3404.2471.11 Application Field and Working Principle

Fuses are electrical, electronic and thermal protection devices used to protect device wiring and components from overload or short-circuit. The 3404.2471.11 is a type of fuse manufactured by 4GK that is designed for machine tools, vending machines, video terminals, construction equipment, and other process control type applications.

Design and Specifications

The 3404.2471.11 fuse is a three-way, type R-F, dynamically fused contactor. It has an operating voltage of 24 VDC with a minimum melting point of 12 VDC. The contactor is rated for an operating current of 2.5A at 24V. It has silver-plated contacts and is designed to be mounted onto a 35mm DIN rail in order to provide protection for wiring and equipment.

The 3404.2471.11 fuse has a single pole, single throw design. It features a isolation contact which is used to open a contactor circuit when an overload or short-circuit is detected. This isolation contact is located on the side of the contactor and can be actuated manually or by an automatic controller.

Mode of Operation

The 3404.2471.11 fuse is designed to be used in a circuit that contains a load which is connected to a power source. When the load is energized, the 3404.2471.11 fuse will detect any current overload, short-circuit or electrical fault in the circuit. If the current values exceed the rated current values of the contactor, the associated isolation contact will open the contactor circuit to stop the current flow and prevent further damage to the load or power source.

When the current overload is detected, the fuse will open and disconnect the circuit, thus preventing further damage to the wiring and equipment. Once the fuse opens, it needs to be replaced in order to restore power to the load. The 3404.2471.11 has a replaceable fuse element which is designed to handle overloads up to 2.5A at 24V.

Advantages of 3404.2471.11 Fuse

The 3404.2471.11 has numerous advantages over other types of fuses. It is designed with a three-way contactor mechanism, allowing for additional levels of protection, including a manual reset switch, LED indicator, and an automated emergency back-up system. Additionally, the fuse has an operating temperature range of -40°C to 80°C and has a melting point of 12 VDC, making it suitable for many industrial applications.

The 3404.2471.11 also features a dynamic, self-resetting design, allowing the contactor to reset itself after a fault. This feature saves time and costs associated with manually replacing a blown fuse element. The fuse element is also rated for a maximum current of 2.5A, which makes it suitable for low-level current applications such as vending machines, video terminals, and process control systems.

Conclusion

The 3404.2471.11 fuse is a 3-pole, type R-F, dynamically fused contactor specifically designed for machine tools, vending machines, video terminals, construction equipment, and other process control type applications. It has numerous advantages over other types of fuses, including a replaceable fuse element, dynamic self-resetting design, temperature range of -40°C to 80°C, and rated current of 2.5A. The 3404.2471.11 fuse is a reliable, cost-effective solution for industrial applications.
