5MTP 2

There have a variety of fuse types on the market to meet the needs of industrial applications. Today, we will talk about one of the fuse types, 5MTP 2, and discuss its application field and working principle.

5MTP 2 is a type of the cylindrical fuse which offers excellent overload protection for a wide range of applications. It consists of a fuse tube, a heat-sensitive material,a connecting element, a quantity of heat-sensitive material and a great number of contact areas. Under normal working conditions, the current flows through the fuse tube in a regular manner.

When an over-current occurs, that could cause a severe damage to the electrical system, the fuse tube will expand from the temperature rise generating the contact areas to break and thereby interrupt the current.

Application Field

5MTP 2 fuses are widely used for residential and commercial facilities, benefiting from the fact they are able to handle both weather-related and electrical power surge problems. Their application fields include:

• Electrical power surge protection in Multiple Dwelling Units (MDUs)
• Fuse protection of HVAC systems
• Protection against water hammer in plumbing systems
• Preventing high energy usage in cables and other electrical components
• Safety protection against system malfunctioning or damage

Working Principle

5MTP 2 fuse technology uses a heat-sensitive material to detect the temperature rise in the fuse tube. When an overload occurs, the high temperature causes the fuse to expand rapidly. This expansion creates pressure on the surface of the fuse tube until the contact areas break, thereby interrupting the current.

Under normal conditions, 5MTP 2 fuses will remain intact until the actual temperature reaches a predetermined value, after which the metal strips expand and the tube itself crackles. When the current is gone, the heat-sensitive material cools and the fuse tube can be used again.

Conclusion

5MTP 2 is a type of cylindrical fuse that offers excellent overload protection for a variety of applications. Its application fields include residential and commercial facilities, HVAC systems, plumbing, electricity, cables, and system safety. The fuse utilizes a heat-sensitive material that triggers an expansion of the fuse tube when an overload is detected. Ultimately, the contact areas break and the current is interrupted. This article provides an overview of the application field and working principle of 5MTP 2 fuses.
