170M5390 Application Field and Working Principle

Electrical specialty fuses are a type of power distribution component used to protect a circuit and its connected components from damage due to overcurrents, including those caused by short circuits and overloading. The 170M5390 is a medium voltage fuse used for the protection of circuit breakers, feeders and branch circuits in commercial and industrial applications. The fuse is available in a variety of ratings and sizes to match circuits of various ratings and sizes.

Characteristics of the 170M5390 Fuse

The 170M5390 fuse is a medium voltage, non-reversible, dual element fuse with an interrupting rating of 45 KA RMS symmetrical. It is designed to be used in installations requiring the highest level of safety, such as those used in hazardous locations. The fuse is under -filled with epoxy encapsulation, which provides the fuse with additional insulation and helps protect it from moisture, vibration, and dust. The fuse rating is marked directly on the fuse.

Technical Specifications of the 170M5390 Fuse

• Rated current range: 500 A - 3000 A
• Rated voltage: 38 kV
• Operating temperature range: -40°C to +85°C
• Interrupting rating: 45 kA RMS symmetrical

Working Principle of the 170M5390 Fuse

The working principle of the 170M5390 fuse is relatively simple. When an overcurrent occurs, it causes the fuse elements to heat up. As the element temperature increases, the fuse material near the element melts, breaking the circuit and preventing any further increase in the current. The cooling gap between the melted material and the fuse terminal, along with the epoxy encapsulation, helps dissipate the heat.

Applications for the 170M5390 Fuse

The 170M5390 fuse is an excellent choice for a variety of applications, such as:

• Power distribution systems in commercial and industrial facilities
• Circuit protection in hazardous locations
• Protection of motors, transformers and other electrical equipment

The 170M5390 fuse is an excellent choice for reliable protection of low, medium and high voltage installations. It is designed to handle short-circuit currents up to 45kA RMS symmetrical and has been tested and certified for use in hazardous locations.
