Fuses

3AP 160-R type fuses, also known as medium voltage power fuses, are manufacturedby Kilovac (or issued by other brands). It is a high-speed, zero recovery time,and quick response power fuse realized by special materials and construction.

Application Field

This type of 3AP 160-R fuse is mainly used in medium voltage power products or equipment, such as transformers, capacitor dividers, generators, motors, etc. The fuses are widely used in many industries, such as electric utilities, railroads,electronic equipment, chemical, petrochemical, offshore oil exploration and production, etc. It is available with a variety of accessories to suit a range of applications. These 3AP 160-R fuses have been tested and certified for safety.

Working Principle

When the current flowing through the fuse body of the 3AP 160-R exceeds its rated current, the internal resistance increases rapidly, thus generating heat, and causing the fuse to open. The melting wire is then cut off and a relatively large contact gap is realized, resulting in interrupting the current.

One of the unique features of 3AP 160-R fuses is the extremely quick and clean. The interrupting curve of this type of fuse is free from any recovery time, meaning the current can be stopped and separation achieved at ÓÐÐÞ, with minimal voltage drop and almost no arcing. This feature reduces equipment failure, increases system reliability and ensures a safer working environment.

The melting wire of the 3AP 160-R fuse shall be made of special alloy, which has a high melting point and a low reactivity. Its construction also requires no separators and the whole body is filled with sand and bitumen, designed to absorb heat build-up and confinement of fragments after operation. This important feature makes the 3AP 160-R fuse an ideal choice for safety.

Conclusion

The 3AP 160-R type fuse is highly reliable, fast and clean when it comes to controlling the system current, whether it is in the normal working environment, or when a fault occurs. It is able to react quickly and interrupt the current smoothly. It is capable of protecting various electrical equipment from damages and enhancing the safety of personnel.
