The **8536SHO2V02SX11** is a high-performance NEMA-rated magnetic motor starter from the **Square D** (by Schneider Electric) Type S series. These devices are used to start/stop induction motors and provide overload protection. --- ## 1. Technical Specifications Breakdown The following table summarizes the core electronic and physical attributes of this specific model: | Feature | Specification | | :--- | :--- | | **Product Type** | Magnetic Motor Starter | | **NEMA Size** | Size 6 (Extra Heavy Duty) | | **Poles** | 3-Pole | | **Voltage Rating** | 600V AC (Maximum) | | **Coil Voltage** | 110V AC @ 50Hz / 120V AC @ 60Hz | | **Current Rating** | 540 Amperes (Continuous) | | **Horsepower Rating** | 150 HP @ 200V / 400 HP @ 460-575V | | **Enclosure Type** | Open (No external box) | | **Control Circuit** | Separate Control Circuit | --- ## 2. Key Components & Features ### A. Magnetic Contactor The heart of the device is a heavy-duty solenoid-actuated switch. When the **120V coil** is energized, it creates a magnetic field that pulls the contacts closed, allowing high-current power to flow to the motor. ### B. Overload Protection (S-Type) The "S" in the part number indicates it utilizes a melting alloy or electronic overload relay (depending on the specific sub-configuration). Its role is to sense if the motor is drawing too much current (overheating) and trip the circuit to prevent motor burnout. ### C. Auxiliary Contacts (X11) The **X11** suffix is a specific modification code. In the Square D nomenclature, this usually indicates the inclusion of **one normally open (N.O.) and one normally closed (N.C.) auxiliary contact** for signaling or interlocking purposes (e.g., turning on an indicator light or signaling a PLC). ### D. Separate Control (V02) The **V02** code specifies the coil voltage. This unit is designed to have its control logic (pushbuttons/sensors) powered by a separate 120V source rather than pulling from the main high-voltage line. --- ## 3.
