The **8536SHO2V07** is a specific model of a NEMA-rated magnetic motor starter manufactured by **Schneider Electric (Square D)**. It is primarily used for industrial motor control applications to start, stop, and protect electric motors. --- ## 1. Technical Specifications Below are the primary electrical and mechanical specifications for this specific part number: | Feature | Specification | | :--- | :--- | | **Manufacturer** | Schneider Electric (Square D) | | **Product Type** | NEMA Magnetic Motor Starter | | **NEMA Size** | Size 6 | | **Continuous Current** | 540 Amperes | | **Phase** | 3-Phase | | **Coil Voltage** | 550V AC @ 50Hz / 600V AC @ 60Hz | | **Enclosure Type** | Open (No cabinet/housing) | | **Overload Type** | Melting Alloy (Sold separately) | | **Horsepower Rating** | 400 HP @ 460/575V AC | --- ## 2. Key Electronic & Mechanical Components The 8536SHO2V07 consists of several critical sub-assemblies that work together to manage high-power loads: ### A. The Contactor (Power Stage) This is the heavy-duty switch. When the control coil is energized, it creates a magnetic field that pulls the power contacts shut, allowing electricity to flow from the source to the motor. * **Contacts:** Made of silver-cadmium oxide for high conductivity and resistance to welding. * **Arc Chutes:** Designed to extinguish the electrical arc generated when the contacts open under load. ### B. The AC Magnetic Coil (Control Stage) The **V07** suffix in the part number indicates the specific voltage for the control coil. * **Voltage:** 600V AC at 60Hz. * **Function:** It converts electrical energy into mechanical movement to actuate the starter. ### C. Overload Relay Block While the 8536 series uses **Melting Alloy** thermal units, they are essential for motor protection. * **Protection:** It monitors the current drawn by the motor. If the motor draws too much current (overload), the thermal units heat up, melt a specific alloy, and trip a mechanical switch that cuts power to the coil, stopping the motor. --- ## 3. Nomenclature Breakdown Understanding the part number helps identify the specific electronic configuration: * **8536:** Square D Type S Non-Reversing Magnetic Starter. * **S:** Identifies the physical series. * **H:** NEMA Size 6 (Rated for very high current/industrial applications). * **O:** Open style (designed to be mounted inside a custom control panel). * **2:** 3-Pole configuration (for 3-phase motors). * **V07:** 600VAC / 60Hz Coil Voltage rating. --- ## 4.
