Allen-Bradley 592-EEFC Solid State Overload Relay

Allen-Bradley 592-EEFC E1 Plus Solid State Overload Relay is a three-phase overload protection device designed to mount to NEMA contactors sized 0 through 2, providing end-of-line protection integrated into standard motor control circuits. It offers an adjustable overload current range of 9–45 A (three-phase), enabling coordination with motor nameplates and drive systems, and supports selectable trip classes of 10, 15, 20, or 30 to match system protection schematics. The unit is a solid-state overload relay in the E1 Plus family (Bulletin 193/592), with a choice of automatic or manual reset to suit different control philosophies, and it is intended to interrupt current when overload conditions are detected to help prevent motor damage. Intended for use with Allen-Bradley contactors and standard control wiring, this overload relay works as part of a compact starter assembly, reducing the need for separate protective devices while maintaining diagnosable protection through conventional signaling terminals. For installers and technicians, the 592-EEFC combines clear current control, configurable trip behavior, and straightforward mounting to common NEMA contactors, aligning with Allen-Bradley motor control catalog conventions for 3-phase protection.
