The **8536SDO2V02S** is a specific model of a NEMA-rated magnetic motor starter manufactured by **Square D (Schneider Electric)**. It is part of the Type S product line, designed for starting and stopping AC motors while providing thermal overload protection. --- ### Technical Specifications Breakdown The following table outlines the core electronic and mechanical characteristics of this specific unit: | Parameter | Specification Details | | :--- | :--- | | **Manufacturer** | Square D (Schneider Electric) | | **NEMA Size** | Size 2 | | **Continuous Ampere Rating** | 45 Amperes | | **Poles** | 3-Pole (3-Phase operation) | | **Control Voltage (Coil)** | 110V AC @ 50Hz / 120V AC @ 60Hz | | **Enclosure Type** | Open (No metal box/NEMA 1 cabinet) | | **Overload Type** | Melting Alloy (requires separate thermal units) | | **Phase Support** | 3-Phase | | **Motor Power (HP)** | 10 HP @ 200V / 15 HP @ 230V / 25 HP @ 460-575V | --- ### Key Electronic Components #### 1. Magnetic Contactor The heart of the device is the magnetic contactor. When the **120V AC coil (V02 suffix)** is energized, it creates an electromagnetic field that pulls the power contacts closed, allowing high-voltage electricity to flow to the motor. #### 2. The Coil (V02 Code) The "V02" in the part number specifically designates the coil voltage. This part is designed to interface with standard North American control circuits (120V). - **Frequency:** Operates on both 50Hz and 60Hz. - **Inrush/Sealed VA:** The coil draws higher current initially to close the contacts (Inrush) and then drops to a lower current to hold them closed (Sealed). #### 3. Overload Relay Block This unit features a "Melting Alloy" overload relay. - **Thermal Units:** It requires the installation of "B-type" thermal heaters (sold separately) matched to the motor's Full Load Amps (FLA). - **Protection:** If the motor draws too much current, the heat melts a low-temperature alloy in the heater, tripping a mechanical link that opens the control circuit and shuts down the motor. #### 4. Auxiliary Contacts The "S" suffix often denotes specific configurations or separate control features. Standard Type S starters usually include one normally open (N.O.) auxiliary contact, used for "holding" the circuit in place when a momentary "Start" button is used. --- ### Part Number Suffix Decoding | Segment | Meaning | | :--- | :--- | | **8536** | Product Type (Non-reversing Motor Starter) | | **S** | Series / Design Type (Type S) | | **D** | NEMA Size (D = Size 2) | | **O** | Enclosure Code (O = Open Style) | | **2** | Number of Poles (3 Poles) | | **V02** | Voltage Code (120V AC Coil) | | **S** | Separate Control Circuit capability |
