2108008.MXP Application Field and Working Principle

Fuses are widely used in the industrial and commercial fields, especially in currents not exceeding 690V. In these fields, 2108008.MXP (miniature, eXtreme Performance current limit Fuses) respond quickly to short-circuit and overload current, providing added protection and improved safety. This article will explain the application field and working principle of 2108008.MXP.

Application Field of 2108008.MXP

2108008.MXP are designed for single-phase AC circuits, motor circuits, and other industrial and commercial current applications, and they are available with various ratings, such as 400VAC, 600VAC, and 690VAC. The fuse is also UL 248-14 listed, rated 1500A at 125VAC and has a wide current range.

Due to the small size, high performance, and wide application range of 2108008.MXP, the fuse has seen widespread use in industrial and commercial current applications, especially as the current requirements increase in proportion to the size of the device. In particular, motor circuit protection, multi-conductor cable protection, and rectifier protection for DC power supply require a high current-carrying capacity and a short operation time.

Working Principle of 2108008.MXP

The current-limiting technology utilized by 2108008.MXP fuse protects circuits by allowing the fuse to blow quickly as soon as an overcurrent condition is sensed. This is achieved by the patented bi-metallic heat sensing elements located in-series with the fuse. When an overcurrent is detected, these bimetallic elements deform, leading to an increased resistance in the fuse which causes it to blow.

The fast-acting capability of 2108008.MXP fuses enables them to respond quickly to short-circuit currents and explosively open regardless of fault duration. The fast-acting property provided by the bi-metallic sensing elements also improve safety for nearby personnel or equipment located near the fault. Furthermore, the 2108008.MXP has an arc cloud extinguishing feature which prevents energized particles or arcs from leaving after the fuse is opened, ensuring even greater safety.

Conclusion

2108008.MXP fuses are designed to provide reliable protection against short-circuits and overloads while being compact in size. Utilizing the bi-metallic heat sensing elements in-series with the fuse, 2108008.MXP provides fast and full current-limiting protection. In addition, its arc cloud extinguishing feature keeps energized particles or arcs from leaving after the fuse is opened, ensuring greater safety for applications that require a high current-carrying capacity and a short operation time.
