KTU-3001

KTU-3001 Application Field and Working Principle

The KTU-3001 is an intelligent low voltage (LV) fuse manufactured by DKJ Electrical Ltd. It is specially designed for a number of applications in LV power systems, from industrial and commercial plant to house wiring and consumer networks. As a result, it provides reliable protection for LV electrical equipment from possible damage due to over-voltage or over-current.

The most important features of the KTU-3001 include:

• Automatic thermal reset
• High rated current up to 70A
• Copper-to-steel transition
• Fulfills IEC60947-1 & IEC60947-2 standards

The KTU-3001 replaces a variety of conventional fuses in LV systems, such as its screw-in MCBs, circuit breakers and time-delay fuses. It has been specifically designed to protect against over-voltage and over-current, providing an extra layer of protection.

When the electrical current passing through the KTU-3001 exceeds its rated value, the internal thermal device will cut off the current. This prevents the LV power system from potential damages due to over-current or over-voltage. As the electrical current returns to within the safe limits, the thermal device will reset the system automatically.

The KTU-3001 is rated for a range of operating temperatures and currents. Its rated current may reach up to 70A, while its rated operating temperature can range between -20 and +120 degrees Celsius. What’s more, its copper to steel transition temperature remains below +40°C.

The KTU-3001 is certified to meet IEC60947-1 and IEC60947-2 standards. It provides reliable protection from short circuit and overvoltage. It is also shock and dustproof, making it safe to use in industrial environments.

The importance of good electrical protection devices cannot be overemphasized. The KTU-3001 is the perfect choice for LV power systems as it can provide reliable protection from over-voltage or over-current, ensuring the safety and stability of electrical systems.
