The **8502SHO2V06** is a specific model of a NEMA-rated magnetic contactor manufactured by **Schneider Electric (Square D)**. It is primarily used for switching electric power circuits, typically for motor control or lighting loads. Below is a breakdown of its electronic and electromechanical specifications. --- ### 1. General Specifications The model number follows the Square D nomenclature, where each character defines a specific attribute. | Attribute | Specification | | :--- | :--- | | **Product Type** | Type S Magnetic Contactor | | **NEMA Size** | Size 0 | | **Continuous Ampere Rating** | 18 Amperes | | **Number of Poles** | 3-Pole (3P) | | **Enclosure Type** | Open (No external box/housing) | | **Control Circuit** | Separate Control Circuit | --- ### 2. The Coil (The "V06" Suffix) The suffix **V06** is the most critical electronic detail as it specifies the operating voltage of the electromagnetic coil inside the device. * **Coil Voltage:** 440V AC @ 50Hz / 480V AC @ 60Hz. * **Function:** When 480V is applied to the coil terminals (A1/A2), it creates a magnetic field that pulls the power contacts closed. * **Power Consumption:** It has a specific "Inrush" (to close) and "Sealed" (to stay closed) VA rating to prevent overheating. --- ### 3. Power Contacts & Ratings The electronic capability of the main terminals is defined by the NEMA Size 0 standard. * **Maximum Voltage:** 600V AC. * **Horsepower (HP) Ratings:** * 200/230V AC: 3 HP * 460/575V AC: 5 HP * **Phase:** Designed for 3-Phase systems but can be wired for 1-Phase. --- ### 4. Component Breakdown | Part | Description | | :--- | :--- | | **Molded Coil** | Encapsulated to resist moisture and physical damage. | | **Silver Cadmium Oxide Contacts** | High-conductivity tips designed to resist welding and arc erosion. | | **Armature/Magnet** | The mechanical link that moves when the coil is energized. | | **Terminals** | Screw-clamp type designed for copper wire (typically 14-10 AWG). | --- ### 5. Wiring Logic The **8502SHO2V06** is a "non-reversing" contactor. It does **not** include an integrated overload relay (that would be an 8536 series). ```text [L1] [L2] [L3] <-- Line Input (480V) | | | [Contactor] <-- Coil energized by 480V (Terminals A & B) | | | [T1] [T2] [T3] <-- Load Output (Motor/Heater) ``` ---
