The model **8536SHO2V02H30S** is a specific 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 | Part Category | Description | | :--- | :--- | | **Type (8536)** | Indicates a NEMA Type S Magnetic Starter. | | **Size (SH)** | Refers to **NEMA Size 2**. This defines the physical size and current handling capability. | | **Configuration (O)** | Indicates an **Open Type** construction (no enclosure, intended for mounting inside a control panel). | | **Coil Voltage (V02)** | Specifies a **120V AC / 60Hz** (or 110V AC / 50Hz) control coil. | | **Overload (H30)** | Features a Motor Logic **Solid-State Overload Relay (SSOLR)**, Class 10/20 selectable. | | **Options (S)** | Indicates a separate control circuit (the coil power is separate from the motor power). | --- ### 2. Technical Specifications | Parameter | Rating / Value | | :--- | :--- | | **Current Rating** | 45 Amperes | | **Phase** | 3-Phase | | **Number of Poles** | 3-Pole | | **Max HP (200-230V)** | 15 HP | | **Max HP (460-575V)** | 25 HP | | **Coil Voltage** | 120V AC | | **Overload Type** | Solid State (Adjustable range) | --- ### 3. Key Electronic Features #### Magnetic Contactor The heart of the device is a magnetic contactor. When the **120V V02 coil** is energized, it creates a magnetic field that pulls the power contacts shut, allowing electricity to flow to the motor. #### Solid-State Overload Relay (H30) Unlike older "melting alloy" heaters, the **H30** designation refers to a modern solid-state relay. * **Protection:** It monitors current electronically and trips if it detects an overcurrent condition, phase loss, or phase unbalance. * **Adjustability:** It allows the user to dial in the specific Full Load Amps (FLA) of the motor without changing physical parts. #### Separate Control Circuit (S) The **"S"** suffix means the control transformer or external power source provides the 120V for the coil, rather than pulling it directly from one of the high-voltage motor lines. This is a safety feature for control panels. ---
