Introduction

3404.0043.11 are fuses designed to protect electrical circuits against overloads and short circuits. They are suitable for general-purpose industrial and commercial applications, as well as for household use. The fuse has a low-resistance sensing element that is connected in series with the protected circuit. When an overload or short circuit condition occurs, the fuse reacts by opening the circuit and thereby prevents the current from continuing to increase. In essence, the fuse acts as a safety valve and offers superior protection, even during the transient phase of an overload or short circuit condition.

Principle of Operation

When a current flows through the fuse element, it heats up. The heated portion of the fuse elements begins to melt, resulting in an increase in resistance. As the melting process continues, the resistance of the fuse element increases to a point where the current flowing through the fuse can no longer be sustained. The fuse then “blows” or opens, effectively interrupting the current flow. Depending on the load on the protected circuit, the fuse may take several milliseconds to blow. If the current flow is too high, the fuse may blow instantly.

Characteristics of the 3404.0043.11 Fuse

The 3404.0043.11 fuse has several characteristics. For instance, it has a high breaking capacity of 400A and a high interrupting capacity of 500A. The fuse also has a voltage rating of 690V. The fuse is UL and CSA approved and is coated with a specially formulated compound for greater protection. The fuse also contains a visual indicator which indicates when the fuse has operated. This allows the user to check whether the fuse has blown and needs to be replaced.
