The **8502SDO2V06** is a specific model of a non-reversing magnetic contactor manufactured by Square D (Schneider Electric). It is part of the Type S product line, primarily used for controlling electric motors or resistive loads in industrial environments. ### 1. Technical Specifications The following table highlights the core electrical and physical characteristics of the device: | Feature | Specification | | :--- | :--- | | **Product Type** | Magnetic Contactor | | **Series** | Type S (NEMA Style) | | **NEMA Size** | 2 | | **Continuous Current Rating** | 45 Amperes | | **Pole Configuration** | 3-Pole (3P) | | **Coil Voltage (V06)** | 440V AC @ 50Hz / 480V AC @ 60Hz | | **Enclosure Type** | Open (No housing/cover) | | **Auxiliary Contacts** | None (Base configuration) | --- ### 2. Key Components & Features * **The Coil (V06 Code):** The suffix `V06` signifies the control voltage. This contactor requires 480V (60Hz) to energize the electromagnet and pull the contacts closed. * **The Contacts:** Heavy-duty silver-cadmium oxide contacts designed to withstand high-inrush currents without welding or excessive pitting. * **NEMA Rating:** Unlike IEC contactors, NEMA Size 2 contactors are "over-built" for longevity and are easily maintainable (parts can be replaced individually). * **Mounting:** Designed for panel mounting within a larger electrical cabinet. ### 3. Functional Operation 1. **Energization:** When 480V is applied to the coil terminals (A1/A2), an electromagnetic field is created. 2. **Actuation:** The field pulls the armature down, overcoming the return spring and closing the 3 main power poles. 3. **Power Delivery:** Electricity flows from the line side (L1, L2, L3) to the load side (T1, T2, T3). 4. **De-energization:** When control power is removed, the spring forces the contacts open, disconnecting the load. ### 4.
