## Overview of the KTS-R-6 Fuse The **KTS-R-6** is a high-performance industrial fuse manufactured by **Bussmann (Eaton)**. It belongs to the **Limitron™** family and is classified as a **Class RK1** fuse. This component is specifically designed for high-degree current limitation and short-circuit protection in electrical systems. --- ### Technical Specifications The following table outlines the primary electrical characteristics of the KTS-R-6: | Feature | Specification | | :--- | :--- | | **Part Number** | KTS-R-6 | | **Amperage Rating** | 6 Amps | | **Voltage Rating (AC)** | 600 Vac (or less) | | **Interrupting Rating** | 200,000 Amps RMS Symmetrical | | **Fuse Class** | Class RK1 | | **Response Characteristic** | Fast-Acting | | **Material** | Melamine glass tube with silver-plated end caps | --- ### Key Features and Design 1. **Current Limitation:** As a Class RK1 fuse, the KTS-R-6 provides a very high degree of current limitation. It reacts significantly faster than RK5 fuses, reducing the "let-through" energy during a fault, which protects sensitive downstream components. 2. **Physical Dimensions:** It features a cylindrical cartridge body with ferrules (end caps). The "R" in the part number indicates it is **rejection-style**, meaning it has a physical notch that prevents it from being replaced by a lower-rated fuse (like Class H or K) in a dedicated Class R fuse holder. 3. **Fast-Acting:** Unlike "Time-Delay" fuses, the KTS-R-6 is designed to open quickly when an overload or short circuit occurs. This makes it ideal for non-inductive loads. --- ### Common Applications The KTS-R-6 is typically utilized in the following environments: * **Branch Circuit Protection:** Used in electrical panels to protect individual circuits. * **Specialized Equipment:** Protecting resistive loads such as electric heaters. * **Control Transformers:** Providing high-level protection for control power circuits where motor starting surges are not present. * **System Upgrades:** Used to upgrade existing systems to improve short-circuit current ratings (SCCR). --- ### Safety and Compliance The KTS-R-6 adheres to stringent industry standards to ensure reliability: * **UL Listed:** Guide JDDZ, File E4273. * **CSA Certified:** Class 1422-02, File 53787. * **RoHS Compliant:** Manufactured without hazardous substances.
