Fuses Description

Fuses are small component devices used in electrical systems to protect circuits from overload. A fuse easily lacks in and out continuity when an overload or fault current exceeds its rated current. A 0697H0315-01 is one type of fuse widely used in industrial applications, such as motors, pumps, solenoids and other SCR or Triac controlled circuits.

Application Field

The 0697H0315-01 Fuse is especially suitable for general electrical protection in electronic equipment for motor overload protection, panel board, and bus bar. It comes in three ratings, 15A, 20A, and 30A, 600V AC/DC, and is UL Listed for 1-Cell and 2-Cell Enclosures. It is also cUL certified to both requirements for 125V Class-R and 250V Class-R dual fuses.

Working Principle

The 0697H0315-01 Fuse is typically a non-reusable, one-time, short-circuit protection device that responds rapidly to a wide range of overcurrents ranging from nearly zero all the way to thousands of amperes. When the current flowing through the fuse exceeds the rated value, the fuse link means constructed of an appropriate metal alloy melts, allowing the electric current to stop flowing. This fuse is composed of a transparent plastic tube containing two contacts on each end. The contacts are connected together by a metallic strip inside the tube, commonly referred to as the fuse link. The fuse link is made of a special metal alloy that melts at a predetermined temperature that is determined by the current rating of the fuse. The fuse responds very quickly to sudden changes in current levels and the current can be reduce to nearly zero within microseconds. It is considered to be one of the fastest protection devices available.

Installation Guidelines

When installing the 0697H0315-01 Fuse, it is important to make sure that the wire size and conductor insulation are rated to adequately handle the current that the fuse is designed for. The fuse must be rated for the correct voltage rating and type. If the fuse is to be used in a two-cell enclosure, the fuse must be rated for dual purpose. The fuse must also be positioned correctly in the enclosure and be securely tightened with the lugs provided. If it is not secured properly, the fuse can vibrate, thus causing it to overheat and possibly fail. The fuse must be enclosed within a flame retardant enclosure that provides added protection from external sparks or flame. Finally, the part must carry the UL label to ensure the fuse meets all UL safety requirements for the application.

Conclusion

The 0697H0315-01 is a one-time, short circuit protection device specifically designed for industrial applications. It is suitable for motor overload protection, panel board, and busbar and is UL listed for 1-cell and 2-cell enclosures. It is composed of a transparent plastic tube containing two contacts connected together by a metallic strip inside the tube. It reacts very quickly to changes in current levels and is considered to be one of the fastest protection devices available. Properly positioning and securing the fuse and enclosing it within a flame retardant enclosure are also important criteria to consider during installation.
