The **KTS-R-15** is a high-performance industrial fuse belonging to the **Limitron™** series manufactured by Eaton (Bussmann Division). It is specifically designed for high-speed response and heavy-duty circuit protection. --- ### 1. Technical Specifications The following table highlights the core electrical characteristics of the KTS-R-15: | Feature | Specification | | :--- | :--- | | **Current Rating** | 15 Amperes | | **Voltage Rating (AC)** | 600 Vac | | **Interrupting Rating** | 200,000 Amps RMS Symmetrical | | **Fuse Class** | Class RK1 | | **Body Material** | Melamine (Fiberglass) | | **Dimensions** | 0.81" x 5.00" (approximate) | --- ### 2. Key Electronic Features The KTS-R-15 is not just a wire; it is a precision-engineered safety component with the following attributes: * **Fast-Acting Response:** Unlike "Time-Delay" fuses (labeled FRS-R), the KTS-R is "Fast-Acting." It is designed to open almost instantaneously when a short circuit occurs, protecting sensitive electronic components. * **Current Limitation:** As a Class RK1 fuse, it is highly current-limiting. This means it physically restricts the amount of peak "let-through" energy that can pass through the circuit during a fault, preventing damage to downstream equipment. * **Rejection Feature:** The "R" in the model name signifies it has a rejection tip. This physical design prevents a user from accidentally replacing it with a lower-rated or non-current-limiting fuse (like a Class H or K5) in a standard fuse holder. --- ### 3. Common Applications Due to its high interrupting capacity and speed, it is typically used in: 1. **Branch Circuit Protection:** Standard industrial power distribution. 2. **Sensitive Equipment:** Protection for rectifiers, non-inductive loads, and SCR (Silicon Controlled Rectifier) devices. 3. **Short Circuit Protection:** Used where high fault currents are possible (up to 200kA). --- ### 4. Comparison: KTS-R vs. KTRS-R It is often confused with its "slow-blow" counterpart: | Fuse Type | Characteristic | Best For | | :--- | :--- | :--- | | **KTS-R (Fast)** | Opens instantly on overload | Resistive loads, lighting, sensitive electronics | | **KTRS-R (Delay)** | Allows temporary surges | Motor starts, transformers, inductive loads | ---
