Eaton Bussmann KTK-R-1-4 Fuse – Fast-Acting

Eaton Bussmann KTK-R-1/4 Fast Acting Fuse Product Description

Eaton Bussmann Series Class CC fuse, specifically the KTK-R model, represents a significant advancement in circuit protection technology. This fast-acting, dual-element current limiting fuse combines high performance with reliability, making it an ideal choice for a wide range of applications. Below is a detailed introduction to this impressive product.

Product Overview

The KTK-R fuse is part of Eaton Bussmann's Class CC series, renowned for its exceptional product performance and ability to meet rigorous line and equipment protection requirements. Designed with a 0.25A rating, this fuse is rejection style, meaning it features a unique design that prevents the insertion of low-rated fuses, thereby enhancing safety and reducing the risk of misapplication.

Key Features

• Fast-Acting and Dual-Element Design: The KTK-R fuse is designed to react quickly to overcurrent conditions, thanks to its fast-acting characteristics. The dual-element construction ensures precise and reliable protection, limiting the fault current effectively and minimizing damage to the circuit and connected equipment.
  Current Limiting Capability: One of the standout features of the KTK-R fuse is its current limiting ability. This fuse can limit the fault current, reducing the stress on the electrical system and protecting downstream components from potential damage.
• High Interrupting Rating: With an interrupting rating of 200kA at 600Vac, the KTK-R fuse provides robust protection against severe short-circuit conditions. This high interrupting capacity ensures that the fuse can safely disconnect the faulty circuit, preventing further damage and ensuring the safety of personnel and equipment.

Class CC Benefits

• Delay and Current Limiting Protection: The Class CC designation signifies that this fuse offers both delay and current limiting protection. This combination allows the fuse to provide precise protection against both overcurrent and short-circuit conditions, ensuring that only the faulty circuit is disconnected, minimizing the impact on the rest of the system.
• Rejection Style for Safety: The rejection style feature of the KTK-R fuse prevents the insertion of fuses with lower ratings, which could lead to inadequate protection or even system failure. This added safety measure ensures that only appropriately rated fuses are used, reducing the risk of equipment damage and downtime.

Applications

The KTK-R fuse is suitable for a variety of applications, including but not limited to small motor circuits, relay circuits, and other control circuits where precise and reliable protection is required. Its compact design and high performance make it an excellent choice for use in industrial, commercial, and residential settings.

Summary

In conclusion, the Eaton Bussmann Series Class CC fuse KTK-R is a fast-acting, dual-element current limiting fuse that offers exceptional protection against overcurrent and short-circuit conditions. With its high interrupting rating, delay and current limiting protection, and rejection style design, this fuse provides a comprehensive solution for circuit protection in a wide range of applications. Its reliability, safety, and performance make it a valuable addition to any electrical system.
