The **8536SHO2V07H30S** is a specific model number for a **Square D (Schneider Electric) NEMA Magnetic Starter**. These devices are used in industrial applications to start and stop motors while providing overload protection. Below is a breakdown of the electronic and electromechanical components based on the model nomenclature. ### Component Breakdown (Nomenclature) | Code | Component Category | Description | | :--- | :--- | :--- | | **8536** | **Product Type** | NEMA Type S Non-Reversing Magnetic Starter. | | **S** | **Size** | NEMA Size 6 (Rated for heavy industrial motor loads). | | **H** | **Enclosure Type** | Open (No specialized box, intended for panel mounting). | | **O** | **Design Type** | Type S starter configuration. | | **2** | **Poles** | 3-Pole configuration (standard for 3-phase AC motors). | | **V07** | **Coil Voltage** | 550V AC @ 50Hz / 600V AC @ 60Hz control circuit. | | **H30** | **Overload Relay** | Solid-state Motor Logic™ overload relay (Class 10/20). | | **S** | **Special Feature** | Separate control circuit (isolated from power lines). | --- ### Key Technical Specifications #### 1. The Contactor (Electromechanical) The heart of the 8536 series is the NEMA Size 6 contactor. - **Current Rating:** Rated for up to 540 Amperes (continuous). - **Power Rating:** Typically supports motors up to 400 HP at 460/575V. - **Silver-Cadmium Contacts:** Designed for high conductivity and resistance to welding under high-inrush currents. #### 2. The Coil (V07) The coil is the electronic component that pulls the contacts closed when energized. - **Voltage:** 600V AC. - **Function:** Uses electromagnetic induction to move the armature. The "S" suffix indicates the coil is powered by a separate source rather than tapping off the main power lines. #### 3. Solid-State Overload Relay (H30) Unlike older "melting alloy" heaters, the **H30** designation refers to a **Motor Logic™ Solid-State Overload Relay**. - **Accuracy:** Electronic sensing provides higher accuracy than thermal bi-metallic strips. - **Adjustability:** Features a dial to set the Full Load Amps (FLA) of the specific motor. - **Protection:** Includes phase loss protection and selectable trip classes (10 or 20). --- ### Summary of Features * **Non-Reversing:** Moves the motor in one direction only. * **NEMA Rated:** Built for durability and long life cycles compared to lighter IEC-rated starters. * **Modular Design:** The overload relay and auxiliary contacts can be replaced or upgraded without replacing the entire starter.
