Fuseholders

Fuseholders are an important electrical device used in homes and businesses to protect circuits from overloads. They are basically a mechanical device that holds or clips onto a fuse and has the purpose of connecting a fuse to a circuit, allowing the fuse to open or close the circuit to protect it from becoming overloaded. Fuseholders come in various shapes and sizes to fit the needs of different applications.

The 4393 Fuseholder is a two-pole, panel-mount device designed specifically for industrial and reinforced wiring. It is a hybrid designed to withstand the harshest outdoor elements, as well as the most demanding applications. It has a UL 94V-0 housing with a panel thickness range of 0.060 inch to 0.092 inch, and has a current rating of 20A, a voltage rating of 600VAC and dielectric strength of up to 2000VAC. Its positive locks ensure quick and secure installations and its dual-piece design allows for easy installation and removal.

The 4393 Fuseholder\'s application fields include general industrial, power, lighting and motor control circuits. In addition, it is also used in hazardous locations when mated with a proper fuse. It is typically installed on a panel mount, but can also be used with DIN rail or toggle clip mounting brackets. It is commonly used in main power panels, branch breaker panels, industrial control panels, AC and DC motor control, UPS systems, emergency generator systems, motor controllers, uninterruptible power systems, surge protection systems, control/status indicators, lighting systems, and more.

The working principle of the 4393 Fuseholder is simple. When the current drawn by the circuit exceeds its rated value, the fuse melts, opening the circuit, thus protecting it from overload. This is known as "overcurrent protection." It is important to ensure that the fuseholder is installed correctly and the fuse is the proper one for the application so that it can protect against overloads and other wiring hazards.

In conclusion, the 4393 Fuseholder is an important electrical device used in industrial and reinforced wiring applications to protect the circuit from overloads. It is a two-pole, panel-mount device, with a UL 94V-0 housing, current rating of 20A, voltage rating of 600VAC and dielectric strength of up to 2000VAC. Its application fields include general industrial, power, lighting and motor control circuits, and it is easy to install with its dual-piece design. Its working principle is that of overcurrent protection, whereby when the current drawn by the circuit exceeds its rated value, the fuse melts, and opens the circuit, thus protecting it from overload.
