KLLU700.X Application Field and Working Principle
The KLLU700.X is a heavy-duty, high performance ceramic fuse designed for various challenging applications. This UL489 listed fuse offers superior durability and reliable performance for a variety of conditions and applications. With a wide range of ratings, current and voltage, this fuse is well-suited for both high-power industrial applications and sensitive electronic equipment.
The KLLU700.X fuse is an effective overcurrent protection device, consisting of a copper tube burned with a ceramic center line, surrounded by melting alloy. The melting alloy in the fuse body melts at a certain temperature, indicating an overcurrent condition. When overcurrent occurs, the melting alloy melts, thus providing overcurrent protection.
The KLLU700.X fuse range covers ratings from 30A to 1000A with a variety of interrupting ratings up to 100kA. It can be used in both AC and DC applications, allowing the fuse to adapt to different levels of overcurrent protection, according to the specific requirements of the application. The fuse also consists of a silver tipping element, which adds inductive surge protection capabilities.
The KLLU700.X is highly resistant to extreme operating conditions, which allows it to be used in any environment. It is rated for temperatures up to 600°C and displays excellent voltage breakdown strength. Also, the design prevents the occurrence of dangerous post-arc faults due to an arcing chamber inside the tube. This reduces the risk of damage to the protected equipment due to the arcing.
The main application of the KLLU700.X fuse is in industrial motor control operations, providing overload and short-circuit protection. It is suitable for installations in motor control centers, low-voltage switchgear, and in applications involving contactors and relays. It can also be used for general electronic equipment and transformer protection.
As far as its working principle is concerned, the KLLU700.X fuse works in two different modes: current-limiting operation and current-interrupting operation. When the current exceeds the fuse’s rated current, the melting alloy in the fuse body starts to melt and the fuse element starts to expand. This causes an abrupt increase in the contact resistance, which in turn limits the current. At the same time, the contact resistance causes a voltage drop in the device, which helps to reduce the amount of energy released by the fault. However, if the current is high enough, the resistor ceramic will break down creating an overpressure which will cause an arc and the fuse will open.
The KLLU700.X is a versatile and reliable fuse, offering superior protection against both overcurrent and overloads. There are many reasons why it is so widely used, with its high current and voltage ratings, its robust construction, and its ability to work in a wide range of temperatures, making it ideal for many applications.
