Fuseholders

A fuseholder is a device used to hold and protect a fuse in an electrical circuit. It is an essential component for safe and reliable operations in electrical power systems, especially in industrial or public utility settings. It comes in a variety of shapes, sizes, and materials and is the key piece in controlling the flow of electrical current.

The type of fuseholder used will depend on the type of fuse being used. For instance, low voltage fuseholders are used for general purpose and other low voltage applications, medium voltage fuseholders are used for medium voltage applications, and high voltage fuseholders are used for high voltage applications. Additionally, some fuseholders are suitable for industrial applications, such as circuit breakers and contactors, and others are suitable for larger, commercial environments, such as safety switches and AC distribution systems.

3622 application field and working principle

The 3622 fuseholder is a dual circuit rated (DC) fuseholder and is intended for use in a variety of different applications. It is rated for both AC and DC current and can handle current up to 36 amperes. The 3622 is commonly used in panel boards, motor control centers, and other devices that require a dual rated fuseholder.

The 3622 has two poles in which the fuse can be inserted. The circuit is completed when both poles are connected to the power source. One end of the fuseholder is connected to the electrical source, while the other end is connected to the load. The fuse is inserted between the two poles, forming a physical and electrical link in the circuit. If the circuit draws too much current, the fuse will open, thus disconnecting the circuit and preventing any further damage.

The 3622 is designed with a variety of safety features to ensure safe and efficient use. It has a built-in cut-off switch that will automatically disconnect the circuit if any temperature within the fuseholder exceeds its predetermined limit. It also has a voltage rating that is higher than the voltage rating of the fuse it is used with, providing additional protection against over-voltage conditions.

In addition to its protective abilities, the 3622 fuseholder is also designed to be easy to install and use. It utilizes a push-in type design, meaning that the fuse can be easily inserted into the holder without the use of any tools. The holder is also designed for easy maintenance. The entire fuseholder can be disassembled with some basic tools, allowing for quick replacement of any worn or damaged parts.
