Allen-Bradley 592-EC2DD Solid-State Overload Relay

The Allen-Bradley 592-EC2DD is an E3 Plus solid-state overload relay that protects motors by monitoring current in the 9–45 A range, providing fast, solid-state protection for industrial AC motors. Designed to mount to a NEMA contactor, it is associated with NEMA contactor size B and forms part of the 193/592 EC family, with internal ground-fault sensing in the EC2 variant for enhanced fault detection. Catalog number 592-EC2DD carries a one-year standard warranty and, according to Rockwell Automation, was discontinued on October 31, 2019, with potential replacements offered within the EC/EC2 family. This relay delivers overload protection through solid-state electronics, integrates with standard motor control circuits in panels, switchgear, and motor-control centers, and is appropriate for applications requiring reliable motor protection in 9–45 A circuits, including 3-phase systems.
