Fuses

Fuses are commonly used devices in industry and homes that protect electrical circuits and wiring from too much current. 0312003.HXP fuse is one type of the fuses and is widely used to protect electrical wiring and components from damage caused by too much current. It has a wide range of application fields and a complicated working principle. This article will discuss its application fields and working principles in detail.

Application Fields

0312003.HXP fuse is primarily used for circuit protection and has a wide range of application fields. It is suitable for overcurrent and short-circuit protection in AC 50/60Hz, rated voltage range up to 690V, and rated current up to 125A. It is also suitable for indoor electric boards, household and similar apparatus, controller and distribution box, overload and short-circuit protection in industry and residential area, etc. It is also UL listed for branch circuit protection.

Working Principle

The working principle of 0312003.HXP fuse is quite complicated. It mainly consists of a fuse element, a shell, a mechanical operating system, and an arc-extinguishing chamber. When the fuse is operating normally, the rated current flows through the fuse, making the fuse element electrically hot. When an overcurrent accident occurs, the fuse element will heat faster than it can dissipate. The heat generated by the current will cause the fuse element to melt and separate the circuit, cutting off the power. At the same time, the mechanical operating system will open the switch to disconnect the power supply. The arc-extinguishing chamber will extinguish any arcs produced when the power is cut off.

In summary, 0312003.HXP fuse is a frequently used fuse with a wide range of application fields and a complicated working principle. It is used for circuit protection and is suitable for both indoor and outdoor uses. The fuse element will heat up under normal operation and will melt and separate the circuit when an overcurrent accident occurs. The mechanical operating system and arc-extinguishing chamber will help to finish the process.
