The part number **8536SHO2V06H672** refers to a specific configuration of a **NEMA Size 6 Magnetic Motor Starter** from the Square D (Schneider Electric) Type S line. These devices are used to start, stop, and protect high-horsepower industrial electric motors. --- ## Technical Specifications Breakout | Component | Specification | Description | | :--- | :--- | :--- | | **Type** | 8536 | NEMA Magnetic Motor Starter | | **Size** | SH | NEMA Size 6 (Rated for high current/HP) | | **Enclosure** | O | Open Style (Requires an external panel/cabinet) | | **Poles** | 2 | 2-Pole configuration (Single-phase or specific DC use) | | **Voltage Code** | V06 | 480V AC, 60Hz / 440V AC, 50Hz Coil | | **Overload Relay** | H672 | Specific electronic or thermal overload configuration | --- ## Electronic & Electromechanical Components ### 1. The Magnetic Contactor The core of this unit is a heavy-duty NEMA Size 6 contactor. * **Current Rating:** Size 6 units are typically rated for a continuous current of **540 Amperes**. * **Switching Mechanism:** Uses an electromagnetic coil to pull in heavy copper contacts to complete the circuit to the motor. ### 2. The Operating Coil (V06) The "V06" designation indicates the electronics governing the actuation of the starter. * **Voltage:** Designed for **480V** industrial power systems. * **Inrush/Sealed VA:** Because Size 6 contacts are physically large and heavy, the coil requires a significant "inrush" of current to close the contacts, which then drops to a lower "sealed" wattage once the circuit is closed. ### 3. Overload Protection (H672) The "H" suffix usually denotes a specific type of **Overload Relay** assembly. * **Function:** It monitors the current flowing to the motor. If the current exceeds a set threshold for a specific duration (indicating a jam or motor fault), the relay trips and opens the control circuit to prevent the motor from burning out. * **H672 Specification:** This often refers to a specific trip class or a specialized electronic sensing module tailored for large-scale industrial loads. ### 4. Auxiliary Contacts This starter typically includes auxiliary contact blocks used for control logic: * **Normally Open (NO):** Used for "seal-in" circuits (keeping the motor running after the Start button is released). * **Normally Closed (NC):** Used for status indication or interlocking with other machinery. --- ## Typical Applications Due to the **Size 6** rating, this specific part is designed for massive industrial loads, such as: * Large centrifugal pumps. * Industrial rock crushers or grinders. * Main air compressor units for manufacturing plants. * Heavy-duty conveyors.
