3404.2321.11

Introduction

Fuses are an important component of electrical protection systems. When an over-current fault occurs, the fuse melts and safely disconnects the circuit, thus preventing the circuit or system from being damaged by high current. The fuse 3404.2321.11 is a three-pole range of current-limiting fuses specifically designed for a protection system in a wide variety of applications. In this article, we will discuss the application field and working principle of the 3404.2321.11.

Application Field

The 3404.2321.11 range of fuses is suitable for a variety of power distribution applications. This fuse is capable of interrupting high fault currents, which can be up to 6kA fault level and can be used in a voltage range of 110V to 500V AC. Its wide range of application makes it an essential component in large switching systems, power supplies, motor control and general industrial applications. It is also used as a backup in important parts of the system, offering protection against short circuits and overloads and thus minimizing the risk of fire and personal injury.

Working Principle

The 3404.2321.11 is a three-pole current-limiting fuse. Each pole has an independent blade to increase the current-limiting capability. The fuse is made up of two elements: a fuse element and an arcing chamber. The fuse element can be made of ceramic material, metal alloy or a combination of the two. The arcing chamber encloses the fuse element and acts as an air gap, allowing current to flow through the circuit when it exceeds the specified energy limit.

The 3404.2321.11 fuse has the ability to limit the surface damage caused by the current, as it is designed with an interrupting capacity rating of 6kA. When a fault or overload occurs, the current through the fuse will exceed its capacity rating, causing it to heat up. This will cause the fuse element to melt, thus breaking the circuit and disconnecting the fault and thus preventing the system from being damaged.

Conclusion

Fuses are an important component of electrical protection systems and the 3404.2321.11 range of current-limiting fuses is specifically designed for a wide variety of power distribution applications. These fuses are capable of interrupting high fault currents and have a wide range of applications in industrial, motor control and general power supply applications. The 3404.2321.11 fuse has the ability to limit surface damage caused by the current, thanks to its interrupting capacity rating of 6kA.
