170M5218 Application Field and Working Principle

The 170M5218 is a type of Electrical, Specialty Fuse. It is made of a coil of fine wire contained in a casing. Its working principle is very simple - when an electric current passes through it for a long time, its wire will heat up and vaporize, breaking the current flow and protecting the circuit from damage.

Application Field

The 170M5218 is mainly used in power supplies and motor drives, both in industry and also in individual households. In industry, it is used to protect transformers, motors, generators, and other items of equipment from damage due to overloads or short circuits. In residential applications, it is used to prevent fire due to over-voltages.

How It Works

When an overload or a short circuit occurs, the high current passing through the fuse wire heats it up. This causes the wire to expand, and the fuse melts, effectively breaking the circuit and preventing any further damage. The fuse prevents the same overload or short circuit from occurring again as it must be replaced.

Specifications

The 170M5218 has a rated current of 200A and a rated voltage of 600VAC. It has a breaking capacity of 200kA at 50kA for 2 seconds. It has a time-current characteristic of 10A-125A/10s-5min, and an instantaneous trip current of 150%. It complies with the UL, CSA, and IEC standards. It is constructed of shock-proof plastic material with high temperature and flame retardant properties.

Advantages

The 170M5218 has many advantages. It is very reliable and cost-effective. Its simple design ensures that it does not require any additional accessories or parts, such as relays or trip devices. It is also small and light, so it is easy to install and does not take up much space. It is also very easy to replace if it is damaged.

Conclusion

In conclusion, the 170M5218 is a type of Electrical, Specialty Fuse. It is used to protect power supplies and motor drives in both industrial and residential applications. It has a high current and voltage capability, and is very reliable and cost-effective. It is also easy to install and replace, making it a popular choice for many applications.
