Fuseholders - 04450704H Application Field and Working Principle

Fuseholders are components which are designed to hold and secure an electrical fuse in order to provide overload protection for devices and circuits. The type 04450704H fuseholder is designed to be used with two rigidly connected parts, which provides protection against shock and vibration. This type of fuseholder is especially suitable for high power applications, such as motor starter and machine control, where a high degree of safety is required.

The basic design of the 04450704H is a two-piece construction, consisting of an upper and lower part. The lower part contains an armature which is designed to snap into the fuse receptacle, providing a secure connection for the electrical wires. The upper part of the fuseholder contains two mounting lugs, which are used to mount the fuseholder into the enclosure. The two lugs are slightly offset from each other to ensure correct alignment of the fuse receptacle.

When the fuse is inserted into the 04450704H, the armature springs into contact with the fuse receptacle, creating a secure connection. When electrical current passes through the fuse, the armature will act as a conductor, carrying the current to the load. If the current starts to increase, the increased heat will cause the armature to expand, releasing the connection and breaking the circuit, thus preventing the load from receiving excessive current.

The 04450704H also offers additional benefits such as vibration and shockproof mounting, which is important in many industrial applications. The two-piece construction ensures that the fuseholder is securely connected to the enclosure, and that it will remain in place even when the device is subjected to shock and vibration. This helps to prevent accidental disconnection of the fuse, which can otherwise result in sudden power outages.

The 04450704H is an ideal choice for high current applications, as it can handle up to 100A. In addition, it is also suitable for use with low voltage systems, as it has an UL-listed rating for use up to 600VAC. The 04450704H is available in both a standard and heavy duty version, depending on the application requirements.

Overall, the 04450704H provides a reliable fuseholder solution, offering protection against overloads and accidental disconnection of the fuse. It is an ideal choice for high power applications, as well as for low voltage systems, due to its rigid construction and UL-rated insulation. It is also available in both standard and heavy duty versions, allowing users to select the right solution for their particular application.
