The **BK/HKP-L-R** is a specific model of a panel-mount fuse holder manufactured by **Eaton (Bussmann Series)**. This component is widely used in industrial and commercial electronic equipment to provide circuit protection. ### Component Breakdown The part number follows a specific nomenclature that describes its physical and electrical characteristics: | Part Segment | Meaning | Description | | :--- | :--- | :--- | | **BK/** | Packaging Code | Indicates bulk packaging (Standard for industrial supply). | | **HKP** | Series Prefix | High-profile, panel-mount fuse holder series. | | **-L** | Feature Code | Indicates the **Long Body** version. | | **-R** | Compliance | Indicates **RoHS** (Restriction of Hazardous Substances) compliance. | --- ### Technical Specifications The HKP series is designed for 1/4" x 1-1/4" (6.3mm x 32mm) fuses, which are standard size for many power applications. | Feature | Specification | | :--- | :--- | | **Voltage Rating** | 250 Volts AC | | **Current Rating** | 30 Amperes | | **Fuse Size Accepted** | 1/4" x 1-1/4" (e.g., AGC, ABC, GBB series) | | **Mounting Type** | Panel Mount (D-hole or round hole) | | **Terminal Type** | Solder / 3/16" Quick Connect | | **Body Material** | High-temperature flame-retardant thermoplastic | --- ### Key Electronic & Physical Features #### 1. "Long Body" Design (-L) The "L" designation signifies a longer housing compared to the standard HKP. This is often used to ensure the electrical terminals are positioned further back from the panel surface, which can be useful for avoiding interference with other components or providing extra clearance for wiring. #### 2. Vibration Resistance The fuse is secured via a **bayonet-style knob**. This requires the user to push and turn the cap to lock it, ensuring that the fuse remains in contact even in environments with high mechanical vibration. #### 3. Safety Certification The BK/HKP-L-R is typically **UL Recognized** and **CSA Certified**. It is designed to withstand a dielectric strength test of over 1,500V, ensuring that the user is safe from electrical shock when replacing the fuse while the panel is powered (though standard safety protocols still apply). --- ### Example Application Circuit The fuse holder is placed in series with the "Hot" or "Line" wire of an AC power input. ```mermaid graph LR A[AC Power In] --> B[BK/HKP-L-R Fuse Holder] B --> C[Internal Transformer/Power Supply] C --> D[Device Load] D --> E[Neutral Return] ``` ---
