0477005.MXP

Fuses play an important role in electronic circuits, especially for protecting components and circuits. 0477005.MXP, a high voltage current-limiting fuse produced by Saftronics, is designed to protect AC motor drives from short circuit and overload. It is widely used in the appliance, industrial, irrigation and agricultural automation markets. This article will discuss the fields of application and the working principle of 0477005.MXP.

Application Fields

0477005.MXP is suitable for an expansive range of applications. It can be used in industrial automation, such as machine and pump protection; various control and distribution panels; heater, transformer, starter, etc. protection; and industrial appliance control and protection. It can be used in the agricultural automation industry, such as livestock raising machinery control and protection, farm vehicle and tractor protection, etc. 0477005.MXP can also be used in the irrigation and water supply industry for water pump and valve protection, and for protecting generator controls.

Working Principle

The 0477005.MXP fuse is a high voltage, current-limiting, thermal type fuse, made from a combination of high resistivity copper alloy and ceramic. This design is highly efficient for short circuit protection. The fuse has two components: an outer casing made from stainless steel and a cylindrical core made of ceramic and a highly resistive copper alloy. When overload or short circuit currents exceed a certain limit, a rapid heating occurs in the copper alloy core, melting the fuse link and breaking the circuit.

The rated current of the 0477005.MXP fuse is higher than other standard fuses. It is designed to open rapidly when the rated current is exceeded, and the breaking time is very short. The fuse is also designed with temperature compensation, providing a consistent performance independent of ambient temperature. This temperature compensation ensures that the fuse will open rapidly when the rated current is exceeded. The maximum fuse breaking capacity of 0477005.MXP is 125KA at 480V AC.

In addition, 0477005.MXP has an integrated visual indication for rapid detection of blown fuse status. The fuse core is designed with red-dotted lines. If the fuse operates correctly, these lines remain intact. When the internal pressure exceeds the rated pressure, the core breaks along the red dotted lines, providing a clear indication that the fuse has blown.

Conclusion

The 0477005.MXP fuse is a reliable and efficient high voltage current-limiting fuse. It is widely used in industrial automation, agricultural automation, irrigation and water supply, and other application fields. Its rated current is higher than standard fuses, with temperature compensation for consistent performance. In addition, it has an integrated visual indication to detect blown fuse status quickly. Therefore, 0477005.MXP is an ideal solution for protecting AC motor drives from short circuit and overload.
