### TPCC-R-2A Electronic Component Overview The **TPCC-R-2A** is a specialized electronic fuse belonging to the **Low-Peak™ Class CC** series. It is a time-delay, current-limiting fuse designed for space-saving protection in electrical circuits. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Current Rating** | 2 Amperes | | **Voltage Rating (AC)** | 600 Vac | | **Voltage Rating (DC)** | 300 Vdc | | **Interrupt Rating** | 200kA RMS Symmetrical (AC), 20kA (DC) | | **Fuse Class** | Class CC | | **Response Characteristic** | Time-Delay (Slow Blow) | --- ### 2. Physical and Material Composition The component is engineered to withstand high thermal and mechanical stress: * **Body Material:** High-grade melamine or fiberglass tube (non-conductive and heat resistant). * **End Caps:** Nickel-plated brass or bronze for high conductivity and corrosion resistance. * **Rejection Feature:** It features a physical "rejection tip" on one end, preventing it from being replaced by a fuse with a lower voltage or interrupting rating in a Class CC fuse holder. --- ### 3. Electronic Functions and Features #### A. Time-Delay Mechanism Unlike "fast-acting" fuses, the TPCC-R-2A can handle temporary surges (inrush current). This is crucial for circuits involving small motors or transformers where a momentary spike in current occurs upon startup. #### B. Current Limiting This fuse is "current limiting," meaning it can stop a massive short-circuit current before it reaches its peak. This protects sensitive downstream components (like semiconductors or contactors) from thermal and magnetic damage. #### C. Color-Coding Typically, these fuses are **Green** in the Low-Peak series, allowing technicians to visually verify the fuse type and rating quickly during maintenance. --- ### 4. Common Applications * **Control Transformers:** Protection against primary-side overcurrent. * **Motor Branch Circuits:** Providing short-circuit protection for small motor loads. * **Industrial Control Panels (UL 508):** Used where high interrupting ratings are required in a small footprint. * **Solenoids:** Managing inductive loads that cause frequent nuisance tripping in standard fuses. ---
