170M7158 is a type of electrical specialty fuse, categorized under its accompanying series name, 170M. The fuses in this series are made to have specific interrupt ratings to protect through a current travelling. Additionally, the 170M7158 has a wide variety of applications and works in a specific principle.

It has a voltage rating of 600 VAC and a range of interrupting ratings from 15-20 kA. This ranges from small loads of electrical current to high DC operation. The unique construction of 170M7158 helps limit the effects of shock and increases safety when using the fuses. The fuse can be cut in a multitude of configurations, including with a “S” or “V” notch to allow for a current utilization rate increase given certain conditions.

The application of the 170M7158 generally centers around industrial installations, motor control centers, IEC HVAC applications, and multi-tapped transformers. This fuse is perfect in applications such as these where the current often changes, as the fuse can be cut into different configurations to better control the current levels. The fuse works by having a predetermined breaking capacity, once that capacity is reached the fuse will break the current to help protect and prevent better safety and better operating conditions.

The fuse is made out of a unique ceramic compounded with a silver alloy. Within the fuse there are a few filaments that when given a current will generate a temperature sufficient enough to melt the alloy. The melting of the alloy will allow current to pass through, which will help protect against overloads. The fuse will disconnect after a predefined amount of current has been reached.

The reaction time of the fuse is very quick, as the current will be cut in a fraction of a second. The specific melting rate of the alloy in the 170M7158 will allow for a low time-current and peak let-through characteristics. It also has the ability to run between cold and hot operations without any major loss of performance.

In addition, the 170M7158 has proven to be very reliable when it comes to cycling operations. This is due to a very low amperage restriction when it comes to fuse and contacts. The contact endurance also helps as it adds more safety when dealing with larger currents. The ability to make certain variations of the fuse can also help when dealing with vast current changes.

The 170M7158 is a reliable and efficient electrical fuse used in a multitude of industrial applications. It can handle large currents by cutting off once a predetermined amount of current is reached, and has been tested and proven to have high performance when dealing with cycling operations. Its construction of ceramic being compounded with a silver alloy has proven to be reliable and assists in low, time-current and peak let through characteristics.
