The **8536SCO2V01S** is a specific model of a NEMA motor starter manufactured by Schneider Electric under the Square D brand. It is a non-reversing, magnetic starter used to control and protect electric motors. --- ## Technical Specifications The following table outlines the core electronic and mechanical specifications for this device: | Feature | Specification | | :--- | :--- | | **Product Type** | NEMA Motor Starter | | **NEMA Size** | Size 1 | | **Current Rating** | 27 Amperes | | **Phase** | 3-Phase | | **Horsepower (HP)** | 7.5 HP @ 230V / 10 HP @ 460V | | **Coil Voltage** | 24V AC (60 Hz) | | **Control Circuit** | Separate Control (indicated by the 'S' suffix) | | **Overload Type** | Melting Alloy (standard) | --- ## Breakdown of Components The 8536SCO2V01S consists of several key electronic and electromechanical parts: ### 1. The Magnetic Contactor This is the primary switching component. When the **24V AC coil** is energized, it creates an electromagnetic field that pulls the power contacts closed, allowing high-voltage electricity to flow to the motor. ### 2. The Overload Relay The "8536" series typically includes a melting-alloy thermal overload relay. * **Function:** It monitors the current drawn by the motor. * **Protection:** If the motor draws too much current (overload), the heat melts a specialized solder formula, tripping a mechanism that opens the control circuit and shuts down the motor to prevent winding damage. ### 3. The Control Coil (V01) The **V01** code in the part number specifically identifies the coil voltage. * **Voltage:** 24V AC. * **Purpose:** This allows the starter to be integrated into low-voltage control systems (like a PLC or a 24V thermostat system) rather than using line voltage for the control logic. ### 4. Auxiliary Contacts The unit usually comes with a built-in "Holding Circuit" (normally open) auxiliary contact. This is used for "3-wire control," allowing the motor to stay running after a momentary "Start" button is pressed. --- ## Part Number Decoder Understanding the "Electronic DNA" of the device through its nomenclature: * **8536:** Type (NEMA Magnetic Starter). * **S:** Square D "S" Series design. * **C:** NEMA Size 1 (up to 27A). * **O:** Open Type (no external metal enclosure included). * **2:** Non-reversing configuration. * **V01:** 24V AC, 60Hz Coil voltage specification. * **S:** Separate Control circuit (no control transformer included; power for the coil comes from an external source).
