The part number **8536SHO2V02H676S** corresponds to a specific configuration of a **Square D (Schneider Electric) Type S Magnetic Starter**. These starters are industrial-grade components used to switch and protect AC motors. Below is a breakdown of the electronic and electromechanical specifications of this part. --- ### 1. Technical Specifications Table | Feature | Specification | Description | | :--- | :--- | :--- | | **Manufacturer** | Square D (Schneider Electric) | Brand / Line | | **Product Type** | NEMA Magnetic Starter | Type S | | **NEMA Size** | Size 6 | Rated for high-current applications | | **Pole Configuration** | 3-Pole | For 3-Phase AC systems | | **Voltage Rating** | 600V AC (Maximum) | Operational voltage limit | | **Coil Voltage** | 120V AC @ 60Hz / 110V AC @ 50Hz | Control circuit power (V02 code) | | **Overload Protection** | Motor Logic Solid State | Electronic overload protection | | **Enclosure** | NEMA 1 | General purpose indoor use | --- ### 2. Breakdown of the Part Number (Nomenclature) To understand the specific electronics inside, we can deconstruct the alphanumeric string: * **8536**: The Class number for NEMA non-reversing magnetic starters. * **S**: The physical design series (Type S). * **H**: Indicates a **Size 6** contactor, which is capable of handling up to **540 Amperes** (Continuous Current). * **O**: Open-style construction (typically used inside a larger control panel). * **2**: Number of poles (though standard 8536H are 3-pole units, this digit identifies the configuration). * **V02**: This is the **Coil Voltage Code**. It specifies that the electromagnetic coil requires 120V AC to pull the contacts closed. * **H676S**: This suffix indicates a specific **Solid State Overload Relay** (Motor Logic) configuration. --- ### 3. Key Electronic Components #### A. The Electromagnetic Coil (V02) The "heart" of the starter is the coil. When energized by 120V, it creates a magnetic field that pulls the heavy-duty power contacts together. * **Inrush VA:** Large (Size 6 coils require significant power to close). * **Sealed VA:** Lower (power required to keep the contacts held shut). #### B. Motor Logic™ Solid State Overload Relay (H676S) Unlike old-fashioned thermal heaters, this unit uses **Electronic Sensing**: * **Accuracy:** Uses internal current transformers (CTs) to monitor motor current. * **Protection:** Provides protection against overloads, phase loss, and phase unbalance. * **Adjustability:** Features a dial to set the Full Load Amps (FLA) of the specific motor it is protecting. #### C. Power Contacts The physical switches made of silver-cadmium oxide. In a Size 6 unit, these are massive components designed to extinguish electrical arcs generated when breaking high-amperage loads. --- ### 4. Typical Applications * Large industrial water pumps. * Heavy-duty manufacturing conveyors. * HVAC Chillers. * Large Air Compressors.
