028707.5U

Introduction

The 028707.5U Fuse has become a common and popular choice when it comes to providing reliable protection for equipment in top-tier electrical and industrial systems. It is designed to offer a number of advantages, including its ability to quickly detect and react to short circuits and overloads, high-grade electrical insulation, and its wide range of application fields. In this article, we will present a detailed overview of this fuse, and how it works in different applications.

Overview Of The 028707.5U Fuse

The 028707.5U is a single-element fuse that is made up of a metallic-film strip encased in an epoxy resin capsule. It has a long-life, fast-response design with an integrated thermal element or “sled” that triggers the fuse’s opening time. It has a breaking capacity of 6.3 kA or 1 kA, depending on the type of installation. The device has a wide range of operating temperatures, from -65ºF up to +250ºF, and can be used for equipment with up to 600 VAC.

The 028707.5U fuse is a reliable and cost-effective solution for overcurrent protection. The thermal sled feature ensures that the fuse will open in a timely and accurate manner in case of short circuit or overload conditions. It has a high degree of reliability and durability, making it an ideal choice for a variety of electrical equipment in both residential and industrial applications.

Application Fields Of The 028707.5U Fuse

The 028707.5U fuse is a versatile device that is suitable for a wide range of applications, such as motor overload protection in HVAC systems, light equipment protection, simple motor control, and other general-purpose applications. It is also used for protecting industrial equipment, such as motors, pumps, compressors, and other sensitive control devices. Other popular applications include power supplies, automotive systems, electric welding machines, elevators, and many more.

In addition, the 028707.5U provides reliable protection for high-voltage equipment that is exposed to a wide range of environmental conditions. Its design makes it robust and reliable in extreme temperature and humidity conditions, and its small size makes it suitable for installation in tight spaces.

Working Principle Of The 028707.5U Fuse

The 028707.5U fuse works on the principle of thermal-magnetic action. This means that the device reacts both to temperatures and to the current flowing through it. When the current exceeds a predefined level, the thermal element (sled) inside the fuse heats up, and starts to expand. This expansion reduces the resistance inside the fuse, resulting in the current increasing even further. The increased current in turn further increases the temperature, resulting in a rapid and effective protection for the equipment.

In essence, the 028707.5U is designed to quickly detect and respond to overcurrent or short circuit conditions. The thermal element ensures that the fuse opens rapidly when the current exceeds predefined levels, thus protecting the equipment it is connected to. It also provides protection from reverse current and induction surges.

Conclusion

The 028707.5U Fuse is a reliable and cost-effective fuse that offers reliable protection for a wide range of applications. It has a wide range of temperature and voltage tolerance, and is suitable for using in harsh conditions. Its fast-response design makes it an ideal choice for sensitive equipment that requires reliable overcurrent protection.
