Specialty Fuses

Introduction to 170M7043 Fuse

The 170M7043 fuse is a type of specialty fuse designed by ABB, which is widely used in industrial and domestic applications. It operates at a rated voltage of 700V and a rated current of up to 145A. The fuse is designed to provide maximum protection to the circuit by interrupting dangerous current levels quickly and safely. This fuse is available in a variety of sizes and is UL listed for recognition.

Application Field and Working Principle

The 170M7043 fuse can be used in a wide range of applications such as protection of commercial, industrial, and residential circuits from overload and short circuit currents. It is suitable for use in AC, DC, and class-2 electrical circuits, and is an excellent choice for high-demand environments. The fuse operates in two different ways- it either interrupts the current when the fault occurs or it opens if the current reaches a threshold level. If the current reaches the threshold level, the two pieces of metal inside the fuse, known as the heating element, fuse together to create an open circuit, thus preventing the flow of current.

Features and Benefits

• Fire-safe design – The 170M7043 fuse features a fire-safe design that ensures the fuse will open in the event of a fire.
• High temperature resistance – The fuse is designed to perform in extreme temperatures up to 150°C.
• Resistant to corrosion – The fuse is designed to be highly corrosion resistant, making it ideal for outdoor and marine applications.
• Excellent protection – This fuse offers superior protection against overloads and short circuits.

Conclusion

The 170M7043 fuse is an excellent choice for a wide range of applications, from residential and commercial to industrial and marine. It features a fire-safe design, high temperature resistance, corrosion-resistant construction, and superior protection against overloads and short circuits. This fuse is UL listed for recognition, making it an ideal choice for many applications.
