Allen-Bradley 500L-COH92 Three-Phase Contactor

Allen-Bradley 500L-COH92 is a three-phase contactor used to switch power to three-phase motors in industrial control panels, enabling reliable on/off operation within automation circuits. It uses a 208V coil, which makes it compatible with 208V AC control supplies and simplifies integration with standard motor-control hardware. The 500L-COH92 designation places this device within Allen-Bradley’s 500L family, helping technicians identify the exact coil configuration and electrical footprint for replacement or drafting of control diagrams. Common applications include starting and stopping motors in conveyors, pumps, fans, machine tools, HVAC equipment, and other industrial machinery where a 208V control circuit is employed. Typical installation contexts include manufacturing lines, process equipment, and building-services applications that rely on three-phase motors controlled by a 208V coil. Verify that the coil voltage and wiring scheme match your system requirements before integration.
