Allen-Bradley 592-EC5DC Solid State Overload Relay

Allen-Bradley 592-EC5DC is a solid-state overload relay in the E3 Plus family, engineered to protect three-phase motors by monitoring line current and tripping on overload. It is rated for a 9–45 A full-load current range, making it suitable for medium-size motors found in conveyors, pumps, fans, and machine tools. Encased in a NEMA 2 enclosure, the relay is designed for indoor industrial environments and pairs with compatible Allen-Bradley contactor assemblies in standard motor-control circuits. As a solid-state protection device, the 592-EC5DC delivers fast, repeatable overload protection to minimize motor overheating and wear, while the E3 Plus designation indicates an updated family of overload relays within Rockwell Automation’s motor-protection lineup. Typical installations wire the relay into the motor-control circuit alongside contactors and fusing, providing coordinated protection for reliable operation on manufacturing lines and HVAC, pumping, or material-handling equipment.
