The **8536SDO2V01S** is a specific model of a NEMA-rated magnetic motor starter manufactured by **Schneider Electric (Square D)**. This device is used to start and stop electric motors while providing thermal overload protection. Below is a breakdown of its core components and technical specifications. ### 1. Component Breakdown The part number can be decoded to understand its specific electronic and mechanical makeup: | Code Segment | Description | Details | | :--- | :--- | :--- | | **8536** | Type | NEMA Magnetic Motor Starter | | **S** | Size | NEMA Size 2 (Rated for higher current/HP) | | **D** | Enclosure | Open Style (No external metal box/can) | | **O** | Design | Non-Reversing | | **2** | Number of Poles | 3-Pole (Typical for 3-phase motors) | | **V01** | Coil Voltage | 24V AC, 60Hz | | **S** | Special Feature | Separate Control Circuit (Control power is separate from motor power) | --- ### 2. Key Electronic & Mechanical Parts #### A. The Magnetic Contactor The heart of the unit. When the **24V AC (V01)** signal is applied to the electromagnetic coil, it creates a magnetic field that pulls the power contacts shut, allowing electricity to flow to the motor. #### B. NEMA Size 2 Contacts These are heavy-duty silver-alloy contacts designed to handle: * **Continuous Amperage:** Up to 45 Amps. * **Horsepower (HP):** Approximately 10 HP at 200V or up to 25 HP at 460/575V. #### C. Thermal Overload Relay (Melting Alloy) This starter typically utilizes a **Motor Logic** or **Melting Alloy** overload block. * **Function:** It monitors the current flowing to the motor. If the current stays too high for too long (overload), the heat melts a specialized solder, tripping the mechanism and cutting power to the coil to prevent the motor from burning out. * *Note: Thermal units (heaters) are usually sold separately based on the specific Full Load Amps (FLA) of your motor.* #### D. Control Circuit (The "S" Feature) Because this is the **"S" version**, the control coil is wired for a **Separate Control Source**. This means the 24V used to trigger the starter does not come from the high-voltage lines (L1, L2, L3) powering the motor; it must be provided by an external transformer or PLC. --- ### 3.
