The **8536SDO2V07** is a specific model of an AC Magnetic Starter from the Square D (Schneider Electric) NEMA Type S line. It is primarily used to start, stop, and protect electric motors. --- ## Technical Specifications The following table outlines the core electronic and mechanical parameters of this device: | Feature | Specification | | :--- | :--- | | **Product Type** | Magnetic Motor Starter | | **NEMA Size** | Size 2 | | **Current Rating** | 45 Amperes | | **Poles** | 3-Pole (3-Phase) | | **Coil Voltage** | 550V AC (60 Hz) / 600V AC (60 Hz) | | **Enclosure Type** | Open (No cabinet/box included) | | **Overload Relay** | Melting Alloy (Thermal) | | **Motor Power** | Up to 25 HP @ 460/575V AC | --- ## Key Components and Electronic Parts The 8536SDO2V07 consists of several modular components that work together to manage high-power motor loads safely. ### 1. The Magnetic Contactor This is the heart of the starter. It acts as a heavy-duty switch controlled by an electromagnet. * **Electromagnetic Coil (V07):** The "V07" suffix indicates the coil is rated for **550/600V AC**. When energized, it creates a magnetic field that pulls the contacts closed. * **Power Contacts:** Silver-cadmium oxide contacts designed to handle high inrush currents without welding shut. ### 2. Overload Relay (Melting Alloy) This part provides thermal protection for the motor. * **Function:** It monitors the current flowing to the motor. If the motor draws too much current (overload), the heat melts a specialized solder alloy inside a "thermal unit." * **Safety:** Once the alloy melts, a spring-loaded mechanism trips the starter's control circuit, disconnecting power to prevent the motor windings from burning out. * **Note:** Thermal units (heaters) are usually sold separately based on the specific Full Load Amps (FLA) of your motor. ### 3. Auxiliary Contacts These are smaller contacts used for logic and signaling. * **Holding Circuit:** Typically includes one Normally Open (N.O.) auxiliary contact to "seal in" the circuit so the motor keeps running after you release the "Start" button. --- ## Wiring and Integration In a typical industrial application, the 8536SDO2V07 is wired as follows: ```mermaid graph TD A[L1, L2, L3 Power In] --> B[Contactor Poles] B --> C[Overload Relay] C --> D[T1, T2, T3 Motor Out] E[Control Switch] --> F[600V Coil V07] ``` ---
