The part number **8536SHO2V02H30SX11** refers to a highly specific, custom-configured NEMA magnetic starter from the **Square D (Schneider Electric) Type S** product line. Below is a breakdown of the electronic and electromechanical components of this device. --- ## 1. Technical Specification Table | Attribute | Specification | | :--- | :--- | | **Product Type** | NEMA Magnetic Starter (Type S) | | **NEMA Size** | Size 6 (Rated for high current) | | **Poles** | 3-Pole (3-Phase motor control) | | **Control Voltage** | 120V AC @ 60Hz / 110V AC @ 50Hz | | **Overload Type** | Motor Logic Solid-State Overload (H30) | | **Enclosure Type** | Open (No cabinet/chassis) | | **Specific Suffixes** | S11 (Custom modification code) | --- ## 2. Key Electronic Components ### A. The Magnetic Contactor (8536) The core electromechanical part is the contactor. It uses an electromagnetic coil to pull in a set of heavy-duty power contacts. * **Coil (V02):** This indicates the control circuit operates at **120V AC**. When power is applied to the coil, it creates a magnetic field that closes the main contacts to start the motor. * **Power Contacts:** Silver-cadmium oxide contacts designed to handle the high-inrush current of large industrial motors. ### B. Motor Logic Solid-State Overload Relay (H30) The **H30** designation refers to a **Motor Logic Solid-State Overload Relay**. Unlike traditional thermal melting alloys, this is an electronic component that provides: * **Phase Loss Protection:** Detects if one phase of the power supply goes missing. * **Adjustable Trip Class:** Allows the user to select Class 10 or Class 20 trip settings based on motor start-up time. * **Ambient Insensitivity:** Electronic monitoring ensures the trip point isn't affected by the temperature of the room/cabinet. ### C. Auxiliary Contacts (X11) The **X11** suffix usually denotes the addition of auxiliary contacts. * These are smaller, low-current switches attached to the side of the main contactor. * They are used for signaling (e.g., turning on a "Run" light on a control panel) or for interlocking with other machinery. --- ## 3. Wiring and Control Interface The device utilizes several connection points for electronic integration: 1. **L1, L2, L3:** Line-in power terminals. 2. **T1, T2, T3:** Load-out terminals (to the motor). 3. **A1/A2:** Coil terminals for the 120V control signal. 4. **95/96 & 97/98:** The NC (Normally Closed) and NO (Normally Open) contacts on the electronic overload relay for fault signaling. --- ## 4. Summary of Naming Convention * **8536:** NEMA Starter. * **S:** Type S design. * **HO:** Size 6 (Heavy Industrial). * **2:** 3-Pole. * **V02:** 120V 60Hz Coil. * **H30:** Solid-state overload relay. * **S11:** Specific internal modifications (often specific mounting or specialized auxiliary contact configurations). ---
