The designation **13A-R** typically refers to a specific type of **Fuse** used primarily in British standard plugs (BS 1363). However, it can also appear in specific power strip or connector part numbers. Below is a breakdown of the technical components and specifications associated with this part. --- ### 1. Primary Identification: BS 1362 Fuse In most contexts, "13A-R" refers to a **13 Ampere, RoHS-compliant (R)** ceramic cartridge fuse. | Component | Specification | Description | | :--- | :--- | :--- | | **Current Rating** | 13 Amps | The maximum continuous current the fuse can carry. | | **Voltage Rating** | 240V - 250V AC | Designed for standard domestic mains electricity. | | **Body Material** | Ceramic | High thermal resistance to prevent shattering during a short circuit. | | **Dimensions** | 6.3mm x 25.4mm | Standard size for UK plug fuses (1/4" x 1"). | | **Breaking Capacity** | 6000A | The maximum current the fuse can safely interrupt. | | **"R" Suffix** | RoHS Compliant | Indicates the part is lead-free and meets environmental standards. | --- ### 2. Physical Construction A standard 13A-R fuse consists of the following electronic/mechanical parts: 1. **Ceramic Tube:** The outer body that provides structural integrity and contains the arc when the fuse blows. 2. **End Caps:** Nickel-plated copper or brass caps that provide electrical contact points. 3. **Fusible Element:** A wire or ribbon (usually silver or copper alloy) designed to melt at a specific temperature. 4. **Filler (Silica Sand):** The tube is often filled with quartz sand to extinguish the electrical arc and absorb heat energy during a failure. --- ### 3. Alternative Use: Connectors and Power Strips If the part number refers to a **Power Distribution Unit (PDU)** or a **Connector**, the "13A-R" designates different features: * **13A:** 13 Ampere current capacity. * **R (Right Angle):** In many electronic components (like IEC connectors), 'R' signifies a **Right-Angle** orientation for cable management. * **R (Rack Mount):** In power strips, it may signify a **Rack-mountable** chassis. --- ### 4. Safety Standards Any electronic part labeled 13A-R must adhere to specific international safety certifications to be legally sold in most regions: ```yaml Standards: - BS 1362: (British Standard for cartridge fuses) - ASTA: (Safety certification mark) - RoHS: (Restriction of Hazardous Substances) - CE/UKCA: (Conformity marking for Europe/UK) ``` ---
