The **ABC-15-R** is a specific model of a fast-acting ceramic tube fuse, commonly used in power supplies, industrial control systems, and electronics protection. It is manufactured by **Eaton (formerly Bussmann)**. --- ### ## Technical Specifications The following table highlights the core electronic characteristics of the ABC-15-R: | Feature | Specification | | :--- | :--- | | **Series** | ABC (Fast-acting) | | **Current Rating** | 15 Amperes | | **Voltage Rating (AC)** | 250 VAC | | **Voltage Rating (DC)** | 125 VDC | | **Interrupt Rating** | 750A at 250VAC / 10kA at 125VAC | | **Body Material** | Ceramic | | **Terminal Material** | Nickel-plated Brass Endcaps | | **Physical Dimensions** | 1/4" x 1-1/4" (6.3mm x 32mm) | | **Compliance** | RoHS Compliant, UL Listed, CSA Certified | --- ### ### Key Electronic Components & Design 1. **Ceramic Tube Body:** Unlike glass fuses, the ceramic body allows for a higher "interrupt rating." This means the fuse can safely handle and break a much higher fault current without the body shattering or exploding. 2. **Fast-Acting Element:** The internal wire is designed to melt almost instantly when a current spike occurs. This is critical for protecting sensitive electronic components that cannot withstand overcurrent even for a fraction of a second. 3. **The "-R" Suffix:** In the Eaton/Bussmann naming convention, the **"R"** stands for **RoHS Compliant**, meaning the part is manufactured without lead or other hazardous substances restricted by European environmental standards. 4. **Nickel-Plated Endcaps:** The terminals are plated to ensure low electrical resistance and to prevent oxidation/corrosion over long periods of use. --- ### ### Applications The ABC-15-R is typically found in: * **Power Supplies:** Protecting the input stage from short circuits. * **Industrial Equipment:** Used in control panels where high-breaking capacity is required. * **Test Instruments:** Protecting internal circuitry from user error or surges. ---
