Introduction to Fuses

A fuse is an electrical safety device that is designed to detect an overload or fault condition and interrupt the electrical circuit to prevent damage to the components of the circuit. Fuses are commonly used on circuit boards, power strips and other electrical equipment.

3412.0119.11 Application Field and Working Principle

The 3412.0119.11 Fuse is a type of fast-acting fuse that is designed to protect against high current and short circuit faults on commercial and industrial power circuits. The fuse is rated up to 1200 A, but typically operates at up to 450 V. It is a ceramic body fuse that is made up of four parts: two brass end caps, an insulating ceramic tube, and a silver-based arced fuse element.

The working principle of the 3412.0119.11 Fuse is based on the thermal and electrical properties of fuse elements. When a fault current passes through the fuse element, the element heats up, melts, and opens the circuit. This forces a break in the circuit to prevent further current flow and damage to equipment. The time it takes for this process to occur is known as the thermal-response time, and is determined by the size and type of fuse element.

As the rated current increases, the thermal-response time increases as well. This is necessary to ensure that the fuse can handle larger currents without causing a premature opening of the circuit. To further improve the performance of the fuse, the 3412.0119.11 has an added feature that prevents over-voltage arcs that could cause damage to the fuse element.

The 3412.0119.11 Fuse is widely used in commercial and industrial applications. It is commonly used on Electrical Control Panels, Motors and pumps, Control relays, Circuit breakers, Power transformers, Lighting systems, and Data lines. Additionally, it is used in various appliances such as televisions, microwaves, and air conditioners.
