The **8536SHO2V06S** is a specific model of a NEMA-rated magnetic starter manufactured by **Square D (Schneider Electric)**. This device is primarily used for across-the-line starting and stopping of AC motors, providing essential protection against overloads. --- ### Technical Specifications | Feature | Specification | | :--- | :--- | | **Product Type** | Magnetic Starter | | **NEMA Size** | Size 3 | | **Poles** | 3-Pole | | **Voltage Rating** | 600V AC (Maximum) | | **Coil Voltage** | 440V AC @ 50Hz / 480V AC @ 60Hz | | **Continuous Current** | 90 Amperes | | **Enclosure Type** | Open (No physical box included) | | **Overload Type** | Melting Alloy (requires separate thermal units) | --- ### Breakdown of the Part Number The alphanumeric code provides specific details about the electronic configuration: * **8536**: Designates a NEMA-rated non-reversing magnetic starter. * **S**: Indicates the physical frame size (Series S). * **H**: Specifies the enclosure type (Open). * **O**: Refers to the internal construction and configuration of the power stage. * **2**: Designates NEMA Size 3 (capable of handling up to 50 HP at 460V). * **V06**: The Voltage Code for the electromagnetic coil (480V AC). * **S**: Indicates a "Separate Control" configuration, meaning the control circuit voltage is sourced independently from the main power lines. --- ### Key Electronic Components #### 1. The Electromagnetic Coil (V06) This is the "brain" of the starter. When 480V is applied to the coil, it creates a magnetic field that pulls the power contacts closed, allowing electricity to flow to the motor. #### 2. Power Contacts Heavy-duty silver-cadmium oxide contacts designed to withstand the high inrush current of industrial motors. In a Size 3 starter, these are rated for a continuous 90A load. #### 3. Overload Relay Block This unit monitors the current flowing to the motor. If the current stays too high for too long (indicating a jam or mechanical failure), the "Melting Alloy" thermal units will heat up, melt a solder film, and trip a spring-loaded switch to cut power to the coil, protecting the motor from burning out. #### 4. Auxiliary Contacts Typically includes one "Normally Open" (NO) contact used for "holding" or "sealing" the circuit so the motor keeps running after you release a "Start" pushbutton. --- ### Wiring Logic Example If you were to interface this with a PLC or a basic Pushbutton station, the control logic generally follows this flow: ```mermaid graph LR A[Start Button] --> B[480V Coil] B --> C[Magnetic Field] C --> D[Main Contacts Close] D --> E[Motor Runs] E --> F{Overload Sensor} F -- High Heat --> G[Trip/Cut Power] ```
