Eaton 8890A-6501 OPCON Overload Relay System

The Eaton 8890A-6501 OPCON Overload Relay System is a motor protection device from Eaton’s Cutler-Hammer OPCON family. Identified by the part number 8890A-6501, this overload relay protects motors in electrical control panels by monitoring current and tripping when overload conditions are detected. In motor-control circuits, OPCON overload relays provide targeted protection against motor overload and startup faults, helping prevent winding damage and unplanned downtime. The 8890A-6501 component is part of a proven protection solution within industrial electrical assemblies that rely on Eaton’s legacy of motor-control technology. As part of the OPCON lineup, it serves to safeguard electrical motors in automation environments and can be coordinated with other protective devices to form a complete motor-protection scheme.
