The **8502SDO2V06_V01** is a specific part number within the Square D (by Schneider Electric) Type S NEMA Contactor series. This component is primarily used for switching power to electric motors or resistive loads in industrial environments. Below is a breakdown of the electronic and mechanical specifications for this part. --- ### 1. Technical Specifications Table | Feature | Specification | | :--- | :--- | | **Product Type** | NEMA Magnetic Contactor | | **NEMA Size** | Size 2 | | **Continuous Current** | 45 Amperes | | **Poles** | 3-Pole (3-Phase) | | **Coil Voltage** | 480V AC @ 60 Hz / 440V AC @ 50 Hz | | **Enclosure Type** | Open (No external box) | | **Phase Control** | 3-Phase | | **Configuration** | Non-Reversing | --- ### 2. Key Electronic Components The "Electronic" nature of this device is largely electromechanical. Here are the core functional parts: #### A. The Electromagnetic Coil (V06/V01) The suffix **V06** usually designates the specific control voltage for the coil. In this case, it operates at **480V AC**. When energized, the coil creates a magnetic field that pulls the armature down to close the power contacts. #### B. Power Contacts * **Material:** High-grade silver alloy to resist welding and arc erosion. * **Function:** These are the heavy-duty terminals that physically bridge the 45A current from the line side to the load side. #### C. Arc Suppressors / Chutes As the contacts open and close, electrical arcs are generated. The 8502 series uses molded arc chutes to quench these arcs quickly, preventing damage to the contacts and reducing electromagnetic interference (EMI). #### D. Auxiliary Contact Options While the base model is a power switcher, it often includes or supports auxiliary contacts (1 NO/1 NC) used for signaling a Programmable Logic Controller (PLC) or status lights. --- ### 3. Part Number Breakdown Understanding the nomenclature helps identify the electronic limits: * **8502:** Square D Class designation for AC Magnetic Contactors. * **S:** Type S design (Standard industrial). * **D:** Size code (associated with NEMA Size 2). * **O:** Open style (intended for mounting inside a larger control panel). * **2:** Number of poles (though typically 3 poles for standard motors, this specific digit can vary based on custom configurations). * **V06:** The voltage code for the electromagnetic coil. --- ### 4. Application Use Case This part is commonly used in: * **Industrial Motor Control:** Starting and stopping large 3-phase motors (up to 25 HP at 460V). * **Heating Loads:** Switching resistive elements in industrial ovens. * **Lighting Panels:** Managing high-wattage discharge lighting circuits.
