The **8536SDO2V06** is a specific model of a NEMA-rated AC magnetic starter manufactured by **Schneider Electric (Square D)**. It is part of the Type S product line, primarily used for across-the-line starting and stopping of AC induction motors. Below is a detailed breakdown of its electronic and electromechanical components. --- ### 1. General Specifications | Feature | Detail | | :--- | :--- | | **Product Type** | NEMA Magnetic Motor Starter | | **NEMA Size** | Size 2 | | **Continuous Ampere Rating** | 45 Amperes | | **Number of Poles** | 3-Pole (3-Phase) | | **Enclosure Type** | Open (No external box) | | **Control Circuit** | Common control circuit (separate source possible) | --- ### 2. Core Electronic & Electromechanical Parts #### A. The Magnetic Coil (V06 Suffix) The suffix **V06** defines the electrical characteristics of the electromagnetic coil. * **Voltage Rating:** 440V AC @ 50Hz / 480V AC @ 60Hz. * **Function:** When energized, the coil creates a magnetic field that pulls the power contacts closed, allowing current to flow to the motor. * **Maintenance:** The coil is replaceable. If the voltage applied does not match the V06 rating, the coil will either chatter (under-voltage) or burn out (over-voltage). #### B. Power Contacts * **Material:** Usually silver-cadmium oxide or similar alloys for high conductivity and arc resistance. * **Function:** These are the heavy-duty "switches" that carry the 45A load. * **Configuration:** 3 Normally Open (N.O.) poles. #### C. Thermal Overload Protection * **Type:** Melting Alloy (Bimetallic options available depending on the specific block). * **Thermal Units:** This starter requires **3 Thermal Units** (Heaters) to be installed separately to function as a motor protector. * **Mechanism:** It monitors the heat generated by the current. If the current exceeds the set limit for too long, a mechanical link trips the control circuit to stop the motor. #### D. Auxiliary Contacts * **Standard:** Usually comes with one Normally Open (N.O.) auxiliary contact (holding circuit). * **Expansion:** You can add additional side-mounted or top-mounted auxiliary blocks for signaling (e.g., to a PLC or pilot light). --- ### 3. Electrical Ratings (Horsepower) The 8536SDO2V06 is rated for the following maximum motor sizes at various voltages: | Voltage | Max Horsepower (HP) | | :--- | :--- | | **200V AC** | 10 HP | | **230V AC** | 15 HP | | **460V / 575V AC** | 25 HP | --- ### 4. Wiring and Control Connection The device features heavy-duty screw terminals: 1. **L1, L2, L3:** Line inputs (incoming power). 2. **T1, T2, T3:** Load outputs (to the motor). 3. **A1, A2:** Coil terminals (where the 480V control signal is applied). ---
